CAT 345D Excavator

Justin Perreault

Hello all! I'm modeling and texturing a CAT 345D Excavator here is my WIP.

I tend to do much more organic models in zbrush. So I'm going to attempt to do this entirely hardsurface model in max. Here is my progression!

gsokol

Looks like a good start to me.

Whats with that weird shading on the underside of the arm?

Darkleopard

looking nice. Cant wait to see them textures

megancheung

its was just started for the first time in over a week, ever heard of taking it easy until the thing warms up?

Lonewolf

looks cool so far, use darker shader for your next wip

Xoliul

Looks like viewport gamma correction is on + you are using the "2 lights" default light. Both are not the best idea, the standard max setup works well enough.

Justin.
Very good work.
i can't wait to see more of ur skillz unleashed.

Justin Perreault

@gsokol: Not too sure, just have the default standard shader and took and grabbed the viewport. Could be a smoothing group I'll investigate.

@megancheung: I'm not sure I understand the question..

@Lonewolf+Xoliul: I'm just using the default standard shader and took and grabbed the viewport. I'll take the time to take some proper renders when It's closer to completion(high Poly)

Here's a quick update of a bit of the base work.

@Mistry10: Thanks again buddi! Will be pushing it:)

Justin Perreault

Much needed update here, this is the highpoly. I have a good friend to thank for rendering this for me. My computer was not up to the task.

Mistry10

Looks sick bro ! Hope to see some uv maps and base textures soon

c0ldhands

That excavator would give any road worker a boner, nice work dude.

Justin Perreault

Long time no update, here's an update on the lowpoly with the shader in action. Early stages of the diffuse and normals applied to the model here. No spec or any other maps at this point.

Getting closer!:poly136:

Mistry10

looking nice bro.
Some of the normals arent popping though (o'm guessing its just the diff on the model right now )
I really like the direction of the textures on the crawl part.
this model will turn out fantastic when your done.

Popolo

This is looking great! Love the high-poly, truly spot-on. Grew up around these kind of machines and cant wait too see this finished.

Subscribed.

Here's another update of the shader. Diffuse is very near complete and here is with the specular map in it's early stages. Looking for feedback on both maps.

Cheers!

Mistry10

Looking sharp overall buddi

Only suggestion on the texture right now is to show some chipped/scratches on the paint ( and or CAT logo) it'll help bring it to life a bit more

I hope you can post your maps soon !

The wheels, underside chassis, etc, anything that has constant contact with the ground is lacking information.

Currently, the machine looks 'dirty', but doesn't exactly tell me what kind if dirty it is, does it work in a chalk mountain, so it has white chalk all over the place? Does it have sand-burns because it's used in the desert? What about mud, does it work in places the UK or Brazil in construction places?

Basically what I'm saying is, anything that is near the ground or has any type of interaction with it will need some 'environmental' dirt, and what kind of place it was used in, currently, the wheels and entire part is 'clean' and has only random layers of dirty which don't tell me it's workload.

The 'burn' on it's backside edge also tells me it's used in a factory of sorts where there is either heat or alot of water and outside exposure involved.

I suggest testing some rougher dirt, like chalk and dusty dirt, just so you get a feel for it before choosing the type of dirt you want.

Justin Perreault

Right on guys. I'll work on both of those suggestions. Here are the maps

Diffuse/spec/normals

ZacD

Your normal map looks like parts of the high poly and low poly were not matching up well, or you should of added some hard edges. It could cause some weird issues with specular highlights and shading.

Popolo

Really starting to like how it's turning out! Though something that really bothered is how clean and shiny it looks, especially on the threads. Also how yellow the model looks, in real life they are pretty saturated. I know that most images you can find on google are of pretty clean models, but these are mostly exhibition models. It would really add to the believability if you added more grime, rust and generel wear and tear

This image at least shows the threads and the "shinyness": http://upload.wikimedia.org/wikipedia/commons/8/8f/2008-08-17_CAT_345B_with_hammer_attachment.jpg

Great work btw

Nice, I spend alot of time around excavators and theres too much dark yellow.. these things tend to stay pretty dayglo older ones dont yellow they go grey/dark desaturated brown from lubricants and soot from the diesel they burn.

deterioration comes from rust and bubbling of the paint which eventually flakes off starting at the joints and hard edges.

The cabins wear and get more dirt from operators getting in and out.

Mistry10

Thanks for posting the maps buddi.
i agree with the comments above.
One thing i noticed a bit in your diff is the AO.
Try colour correcting it to brownish colour.
I think that well help sell a bit more of the dirt
hope that helps dude !

Justin Perreault

Okay thanks for the feedback everyone. Here is a second revision of the shader. Let me know what you think!

Mistry10

Much better
Are you using a coloured spec map ?
One thing I have noticed is the 'hand painted' like lines/markings on the brown flat track area.
I would suggest a more of a photo overlay to help feel more realistic

rolfness

thats brilliant

I know I'm late, but this is fantastic man!

Bonjours la 3d et super elle et téléchargeable??
