Unable to setup RTX Engine in DR

V-Ray V-Ray GPU Issues
1

Hi dear community
I’m testing out the new vray 6 GPU and I found an issue when trying to setup the RTX engine on a slave machine.
On the slave I have an RTX 3080 and the latest vray 60005 downloaded from nightlies.chaos.com.

The new “select rendering devices for vray GPU” UI is pretty simple and I select RTX render engine from the drop-down menu instead CUDA (which is the default engine).

The Log shows: “API Mode was changed to RTX” but if I close and reopen the tool, CUDA returned as if the changes were not saved.

Does anyone experiment the same issue?

Any advice?

Thanks and have a great day

AC

Hello Alessandro.
1. select RTX engine
2. close program
3. restart system

Sorry.
Utility “select rendering devices” only allows you to select GPU devices. It does not allow you to switch the GPU engine.
Which software do you use? 3dmax?

Use the code in startup


vr=renderers.current as string
if ((matchPattern vr pattern:"V_Ray_GPU*")) == true do renderers.production.engine_type = 3 -- 2 CUDA / 3 RTX
