Hey, I recently did a lot of projects with photographers who are used to light cars with Vred, which is a really fast realtime tool. So far, RT is nearly comparable in terms of speed, but a few things just don’t work as expected. So here is my list of problems: 1: Proxies in RT are kind of useless…

Thanks for the feedback; most of these are known items, though they are not trivial to fix. Hopefully things will get better though. Yes, it will be very useful to have the scene - you can send it to vray@chaosgroup.com or our support guys can get you ftp info to upload it. Best regards, Vvlado

I was going to start a new thread but makes sense to add to this list. A few issues from me: 8: I am using a spiral gradient ramp for anisotropy rotation which doesn’t show up in V-Ray RT GPU. 9: The V-Ray light material needs to be a much higher multiplier (even with compensate for camera exposur…

10: V-Ray light material does not update when rendering animation using production RT GPU when using multi sub object materials. Lets say at frame 0 I have a multiplier of 1 and at frame 30 I have a multiplier of 30. But at frame 30 the light stays at multiplier 1 when rendering an animation in prod…

11: Not always possible to turn on motion blur in RT. Its greyed out even though I have it enabled on the physical camera. Some times I can enable it in active shade but not in production. 12: Motion blur doesn’t update in the active shade when adjusting the shutter speed.

13: Affect Diffuse and Specular checkboxes from VraySun don’t have an effect in RT. Still need some time to prepare a scene, but I will send it, I promise. Already got my support ticket :wink:

vlado, can you confirm any of these issues and if/when they will be fixed? Thanks.

Would be nice to get some feedback, too. Especially number 1 and 2 are bugging me a lot.

We don’t have anything for the moment about 1 and 2 unfortunately. 2 can be made to work better on the GPU by flagging the objects as “dynamic” geometry in the V-Ray Object properties dialog, but this does not work in the same way on the CPU. We are working to improve this on the CPU, but it will be…

Actually I lied about 1 ; while we don’t plan to do anything about materials in proxies for the moment, we did work to improve the original issue - the slow transfer of data from the main application to the RT render servers. It should already be a lot better in the latest beta of V-Ray 3.0 Best reg…

I found a few previous posts in regards to motion blur and RT. Even though it is greyed out its still on in the production renderer. This is fine, although confusing
