Hi guys,

I've been racking my brain for the last 5 hours trying to solve this probably super basic texturing problem.

What i'm trying to do is make a texture for this box that is seamless and bends across polygons (similar to uv unwrapping in native c4d).

For the life of me i can't seem to figure out how. I'm at the point where i've reasearched tutorials and just don't quite know what to look for. I haven't been able to figure out if octane supports UV unwrapping. Is this even possible??



Hope someone can shed some light on this, Thanks in advance.

***EDIT: I'm aware of how the box projection method projects the texture. I'm just not sure how to do what i need.

Have you tried 'cubic' projection?

Just use cubic mapping in texture tag and leave the images as default in octane side. It will take how you generated the uv mappings. And be sure that you have a square tilable image.

Hey thanks for replying. Yea, the file i included is set to cubic right now. It doesn't quite work :/ it repeats the pattern but it's from it's own coordinates. I think it needs to be uv wrapped i'm not sure what i'm doing...

Thanks for your reply, i'm afraid that's how i have it now :/ I think that's where i'm struggling. Is there any information (i haven't found any) on uv mapping specific to octane?

I'm finding that the basic uv mapping box tutorials don't work for this complex box. :/

There is no any different for standard or octane materials on uvmappings if you don't use octane projections. Just use default mode of imagetextures without putting projection and transforms.
So this is not octane spesific problem. You should unvrap it and apply any materials.

Hmmm, i'm breaking down your file and i think my little understanding of uv mapping crumbled away. I see what you mean now about not applying any projections in the material itself.

A 4 sided box is simple to understand but it looks like i will need to brush up on the fundamentals of uv mapping again.

Would you be able to explain how you got the UV Map to align?

Thanks again! I owe you a beer!

ok. A few approaches. Set different cubic maps to different selections if it's simple shape. Or convert to uvw tag and edit in UV Edit mode.

Thank you so much Aoktar. I broke these files down and see what you were trying to communicate.

One more question thanks for your patience. If I wanted to do something more complex like turn the pattern 45 degrees this method doesn't work.

Is it possible to unwrap the uv and still have it work with octane? That's the only workaround I cam think of.

Francisco,
i think you are still missing the point. There is not any different to use c4d materials or octane materials. Just do it your uv unwrapping on standard c4d material and later apply one octane material. That will give same results. Only key is not use the Octane projections in Octane imagetexture. It's using uvs by default on creation.

Hey Thanks for your patience again. I totally get it. I did some tests on a basic box and was able to get it to work.

I guess i didn't pose my questions correctly. I was trying to pick your brain to see if the UV-mapping is the best choice since the pattern is complex and doesn't tile seamlessly when angled at 45 degrees (and cause i'm a noob too). I'm asking on UV-mapping specific forums.

Thanks again for your help! You rock!
