Decimal Spider Tank UE4

saksoy

Hey everyone im just doing this big piece well its big for me anyways but it would be great if i had some guidance and feedback to help me get this done. right now im blocking out and playing around with things i can add but i cant see every angle of the tank so any ideas would be great. im looking at other tank references as well. any input would be great ps i will include the warehouse its in but let me just get the hardest part out the way lol

saksoy

added better images any suggestions what to add or remove. i want to start high poly soon.

ANıL İŞBİLİR

Great work. I don't think it needs a high poly version. With proper textures it should look great as it is.

saksoy

Thanks man. just wanted to see if anyone thought of things i couldnt to add or take from the tank to make it better

Ged

the knee pad style armour on yours looks really small, the original looks big and chunky, more big shapes like that should break up the silhouette in really cool ways. good work so far!

saksoy

Ye man you're right. i bulked up and changed the legs a slight bit to match the concept. I think ill move on to high poly now and make this look more complicated for myself lol

saksoy

heres an update of the high poly. sorry its coming along slowly but im still motivated to finish this. going to start the low poly now and the unwrapping after.

saksoy

Hey guys im know i haven't been doing this for a while but im back. I finally found time to carry on. I am now at the baking stage as i have done the low poly and unwrapped it. there are pieces everywhere. i didn't realize how many little pieces i modeled for this tank. i have hit a few issues though. can someone please tell me why im getting these baking issues for some reason i cant figure it out.
i use maya baking and xnormal both the same problem. The cage is fine. normals facing the right way. so im lost and i want this to look good so im being patient with it.

The Rizzler

Lots of gradients. You didn't mention smoothing groups (hard/soft edges I think they're called in Maya?) Maybe check you have them set up to correspond with your uv islands? 
If all else fails, isolate one piece and try to bake it out properly. Once you crack the problem you can fix all the other pieces

saksoy

Thanks Rizzler. i forgot to mention that aswell but ye i check them too and the smoothing groups are right too. im so confused whether i done something wrong without realising. it only happened to like 2 meshes and they are fairly simple shapes too hence why im confused.

Ged

sometimes maya locks my normals and I dont know why, try unlocking normals and re-doing smoothing on those pieces high and low poly, if thats not it then I dont know. You could also try baking without a cage to see if there's any issue with the cage.

saksoy

I honestly dont know how to thank you. for the first time i got help that actually worked first try haha. Im really grateful Ged thanks alot it solved all the problems i was having 

Ged

No problem looking forward to seeing this textured and lit!

Marvjc

looks good, looking forward for the textures!

saksoy

Thanks Guys. here is just where im at. just choosing base materials and colours before i start adding patterns and some scratches dirt ect.

saksoy

Just another update. I watched a few more tutorials for tips and tricks and once i found out abit more i decided to start texturing from scratch.

so what i have done is chosen what material i will have as the base and what parts to apply the materials to.
i then added paint on top of the raw metal so once i start adding some scratch it revels the raw material.

im either going to add the patterns and some writings on the mesh
or
im gong to start to add roughens details scratches leaks dust dirt ect 

if anyone would like to guid me on what i should do next please do

 Your normal map have lots of nasty gradient shading errors just saying.  Maybe it's a normal map basis sync problem?

do you say that because you looked at the normal map picture above? or do you mean you can notice problems on the mesh in substance painter ?

The Rizzler

Try flipping the green channel of the normal map Substance Painter is using, I don't think errors like that should be happening and might actually affect your texturing e.g. the particle brushes

saksoy

thanks guys you were right. i thought that because the zxy was the same as maya i wouldn't have to but looks much better

saksoy

Hey people!!! Finally textured the tank using substance painter so here it is. its rendered in marmoset for now because the project is not completed and i wanted  to show you my progress. Im still going to build the environment and have everything in UE4.

Ged

Hey it looks cool but somethings funky with the normals or normal map? it looks like the shading is broken - like when you do a bake and then edit some verts and the shading groups get messed up.

saksoy

here are my normal maps that i baked in maya as i had alot of pieces. I thought that but its always good to get a fresh pair of eyes.

peanut™

lovely work, my only crit would be from the original concept. The quad legs take too much spacial space and distract the foremost smaller shapes.

saksoy

Thanks Peanut. I'll see if i can do something about that. Im correcting a few of those gradients i understand what you mean now GED

Ged

yeah you can see them clearly on the closest leg in the first picture

saksoy

here are some screenshots again. I sorted some of the normal map gradients and funkyness which has improved it but the bit on the leg in the first picture for the life of me i couldnt figure it out. Ill try again after i build the environment. thanks guys for the feedback. 
Sorry Peanut i tried playing around with the scales but then the leg either looked too thin or it made it too long. im going to have to leave it as it is but thanks for the feedback.

igi

Your biggest issue right now is some normal map artifacts on various places like on the legs. Your normal map would seem fine on the bitmap but can still yield funky results in 3d due to sync mismatching or you might be broken the normals of the mesh you baked afterwards. I'd do a new fresh bake to be exactly sure. 

saksoy

Thanks IGI. I said fuck it let me try one more time as i wanted to get it right and i found the problem and fix it. baked it again and now i dont have the funkyness. Thanks everyone for your honest feedback ill keep updating

saksoy

here are the screenshots of the tank. Now on to the environment

saksoy

Here are some of the props i have done so far. Slowly but surely. 
got alot of props to do 
Once i have done all the props ill jump into substance designer to do the walls and floors

Love the tank piece, well done!  Personally I'd add a bit more wear and tear to the parts closer to the ground, to make it pop a bit more and to give some sense to the damage that the machine took over use.

Dethling

Great work.
The model is really awesome but, in my opinion, the textures don't hold up to it.
Having the same, silver material for the whole body looks very.. strange and dull.

I would try to seperate the parts of the mech more by assigning different materials and colors to different parts of the mech even if this is not the case in the concept piece.
Also the metall propeety of the silver material is very strong. Try to get it down a little bit, armor panels don't really have a metallic look.

How I would change the Material:
- tone down the metal property of the silver material, make it more "tank armor" like
- change the material of the "inner parts" to some dark, unpainted metal
- add a different colored material to the barrel
- add some highlight colors (e.g. yellow "DANGER" lines) to the heavy machinery

thanks guys for the feedback i really appreciate it. thats kl i can always go back and play around with the textures which i was going to do but didn't know how to approach it. i was waiting for some fresh eyes to help me on this.

The last one i didnt understand. where and on what model did you suggest to put the danger lines on ?

Ged

I think dethling means highlight colours like the red and yellow and hazard lines and decals on concepts like this 

Dethling

Exactly this!
I think some small colored parts would make the whole thing more intressting.

saksoy

sorry for the late reply. Been in the zone with the environment. thanks for the feedback guys. now i understand. once i get my environment finished ill go back to edit the tank.

saksoy

hey guys. i haven't done a mesh with glass. so i have this hydrogen tank and im trying to have the glass effect like i have made in substance. i used an opacity map but in ue4 i couldn't set it up. should i have a complete separate material just for the glass bit ? i used alot of my time trying to figure it out so im leaving it to the end to solve it but if anyone got any tips or advice to help me with the problem please do

saksoy

heres the tank updated. i wanted to see if this is what you guys had in mind. 
i changed the base colors 
toned down the metalness
added some yellow lines and hazard lines
mixed different materials and added dark metal materials to the mid leg area

Dethling

That is exactly what I had in mind.
The changes give the model much more fidelity.

Sugus

Really happy to see this placed in an environment! If I were you I would establish some simple camera angles with a first lighting pass. This will allow you to focus your efforts where they are needed to make this piece shine! Good luck and looking forward to seeing this progress.

saksoy

thanks guys. i have added a few more lights and made my floor texture finally. im going to break the floor up abit more once i get the others done. . I just need to decide my camera angles too. hopefully on my next update ill have that sorted out.

saksoy

Just updating again. added more of the lighting i wanted and colour. I still need light maps   
sorry guts i didn't realise my images that i posted where huge. i have Shrunk them down now

saksoy

Just another update with lighting and and more textures.

saksoy

another update. Finishing my last prop. then i need to break up the floor add decals and still need lightmaps.

saksoy

Done the lightmaps, lighting. just going to break up the floor and added a few more things.

saksoy

Finally Done. Heres some screenshots but its still in preview lighting. im going o build the lighting in production today as it takes long. Bit any feedback would be great
