Series of Questions regarding 3D Modelling

SummonedSpirit

Hey guys,

i've started to get into the texturing aspect of 3d modelling and i'm a lil lost. I have a few questions I like to clear my doubts on.

1. Say if I model a  toilet roll and part of that toilet paper is dragging its way down ready to be taken off and used. Can use a 2d transparent png texture for the part of the toilet paper here? 

2. If so must the plane have thickness so it can be seen from the other side? 


3. I have transparent bottles of soap as well, So far what i've done is modelled the soap bottle with an interior. The challenge i'm facing now is how to add the fluid inside?

4. Is there any way to smooth an object just from lighting or maps alone? Say the toilet roll above if i would like to smooth its edges can it be done via normal maps or some form or light setting/ shader setting? I hear about this a lot but I can't find anything on it..

Appreciate the time taken to advise me further!

Yes. You can adjust the vertex normals along the intersection. You would want to match the top vertex normals of the plane , to the ones on the cylinder, that are the closest to the plane.

Also, this thread should be in the Technical talk section.

I'm always confused between the 2 sections haha, Obs what you are referring to I take it is about NO.4? Would that work too if i export the obj to unreal engine as well though?

Obscura

Yes, number 4 and yes it would work. You export an FBX anyways, but yeah, it would work in Unreal, you just need to set it to read the vertex normals from the FBX. Thats a dropdown list on the import dialogue.

Gotcha Obs! I'll take a look at it!

Alrighty here's my attempt on smoothing a low poly. Did I pull it off right? I basically made all vertexes perpendicular to the points the faced

ivanzu

Are you baking normal maps from High poly?

Filip5

Yes.You need highpoly and lowpoly at same place, overlapping each other.

SummonedSpirit

Nah ivan I'm trying another workflow I just model in low poly create a bevel and modify vertex normals to create smooth shading. I wanted to know if it worked out. if as seen in the photo is realistic enough to move on to the texture phase
