Hello,I try to use displacement, but I face a problem when I pluc Octane displacement in to Displacement input of shader (glossy/diffuse doesnt matter). Surface becomes invisible.

I share the printscreen with and without displacement.

What am I doing wrong? :roll: :roll:

Hi, your level of "Height" is astronomic. :)
Check with 0.05.

Cheers, mib

Thank you for reply to my plea :lol:

Unfortunately I tried different values for height. But I will post screenshot and sample model here, to show the problem.

Here the value of height is 0.05, but I tried 0.000001 to 10 with no luck.

I feel that this should be something easy, I just can not figure what is wrong. Can you check sample model? Also what is the difference between displacement input in Diffuse/glossyness node and output node? (also mix shader node?) Which one to use, if none of them works..

P.S. I also tried it in 3ds max plugin, I face totally same problem there :roll:

Such a dead forum.. Usually I really try not to write about problems without look into problem as deep as I can. But really couldn't solve this one. Seems I have to write to support for this one :|

This is not a plugin issue.
Here is a displacement section of OctaneRender manual: https://docs.otoy.com/manuals/products/ ... placement/
It states: "In OctaneRender, Displacement mapping requires a UV Projection present for the object with the displacement in the scene".

So, after you apply UV-mapping to your mesh - you get a correct result.

Thank you so much for help: now it works!

My mistake was assuming that Octane Box Projection is enough for UV projection present.
