OTOY Forums

I am new to Octane and kind of new too 3D infact so any help would be greatly apretiated.

I am having a particular problem with my textures. I have searched the forum and have tried some of the sugestions but can't seem to change my results.
I have a material that i add a displacement map to (4096 x 4096) this creates the leather grain which i am happy with.
I have a normals map (was a bump map previosly) also at 4096 x 4096 that i am using for foldes and creases for specific parts which are working great
but when i try combine the 2 this strange geometric pattern appears.

i have tried using a mix material but it gives the same results.

bit of perspective... I am texturing a leather couch that is UV maped. Each component has its own normals map, while the leather grain is a generic texture for the whole thing.

any suggestions would be greatly appretiated



I am running C4D 17 (updated) and the latest version of Octane.

Hi MISTER_SYD,
in theory should be the opposite, big geometry deformation with displacement and details with norml or bump. For best results in Octane, since it's a bit different compared to other renderer, you should have the leather grain in each normal map transformed in displacement map to work with only one texture. But since you are already happy with the normal maps, have you tried to use the displace texture in the bump map and use it in a mix material with the normal map version?
Note: you can double the power of the normal map to compensate the mix material reduction.

thanks for the tips bepeg4d

will try swoping out the normal and the displacement and let you know how it goes.

thanks again

Ho MISTER_SYD,
you could start with displacement as bump leaving the normal as they are, it should be enough, I guess.
If not enough, you could try with more complex convrsions

Hi Bepeg4D
I landed up creating one texture map with both the creases and the leather texture and using it as a normal map. that seamed to give me the best results.

I tried all kinds of configirations using bump, distortion, normal, mix material and in the end was just easier to have one image file do all the work.

thanks again for the help!!
