Forest Pro (*) / Re: Vray Displacement not working..

« Last post by Nintenjo on August 20, 2025, 12:19:28 pm »

Do you have any suggested alternative workflows i could try to use for worldspace mapping for my displacement that FP would support? I dont really want to 'bake' my displacement meshes since they need to remain live and editable.

Would a OSL triplanar mapping node work instead?

I could consider using UV's but then i need a way to blend it together for seemless texture / tiling.

I’m afraid this is a known limitation. Forest Pack determines the position of each element before rendering begins, but the VRayTriplanarTex map is evaluated later - during the render itself.

Hi,

I’m sorry to hear you’re running into issues. Please avoid using the VRayTriplanarTex map — once it’s removed and the surface is remapped, everything should work fine. I hope this helps.

Best regards,

This dosnt really help since my entirely landscape is mapped using triplanar mapping, is it a bug that i cant use it or simply not supported as it kind of puts a hard stop on this entire workflow i am trying to achieve.

You need to use the effect. see:

I have done exactly that..  still no joy. (i did mention that above).

Forest Pro (*) / Vray Displacement not working..

« Last post by Nintenjo on August 19, 2025, 09:08:54 pm »

I have a mesh thats displaced with Vray Displacement and i am scattering some objects on it with FP, however the displacement is being ignored. I have setup the Effects based on your own tutorials in order to get displacement working but it dosnt seem to for me.

Ive attached images showing the objects scattering correctly in the viewport, but at render time they are not following the displaced mesh.

Ive attached a test scene to help, debug.. Maybe im doing somthing wrong? https://www.dropbox.com/scl/fi/t1hbcuq8wy01mkupaeqy3/DisplacementBug.zip?rlkey=u73jyhnpme9bbwx8pyyoizh4h&dl=0

Forest Pro (*) / Re: Vray DistanceTex FP source.. (dependency loop)

You're welcome, I’m glad it helped. In my quick test with the latest ForestPack and V-Ray 7, the VRayDistanceTex using the surface worked fine in both CPU and GPU modes, though your setup might differ slightly. That said, when it comes to GPU rendering, support for our plug-in is fully managed by Chaos Group.

Best regards,

Thank you that seemed to work, although only with Vray CPU not GPU. But maybe thats a vRay bug?

As in i can instance it? and then make the use surface for scatter invisible in the render? but rendering the result in the clone?
