OTOY Forums

Hi,
I just switched from C4D to Blender and I'm using Octane 2.0 and the current Blender Plugin.
I have some problems with the mapping of materials and hope that somebody can point me in the right direction.

The image below shows three cubes rendered in Blender with Octane.
All three cubes have applied the same material.
The upper cube is just a default blender cube.
The one in the middle is a cube with some part cut using the Blender Boolean modifier.
The lower cube is created by a spline and the extrude parameters of the spline.

As you can see, even though the same material is applied, the reflections and the projection of the environment is totally different.
Do you have any idea why and how to avoid this?
Any help appreciated.

Hi Jan

I'm sorry, but my imagination is definitely not enough to see the cubes on your pictures.

Jan - Do you have the camera inside the cubes? Also did you UV unwrap them? Octane needs UV's for textures.

@Saramary: I'm using front projection to better illustrate the problem. Therefore you only see one face of the cubes.

@grimm: No, the camera is outside the cubes but you only see the front side. Yes I've unwrapped the UVs.

I found out that the problem goes away if I replace the Octane UV-Projection node by a Octane Box-Projection node but this can't be a solution.
For some reasons UVs that are created by the Blender unwrap option are not correctly interpreted by the Octane UV-Projection node.
Even for simple objects it doesn't work for me.
Is this a bug or am I doing something wrong???
