Upcoming improvement in RT GPU

[thanulee]

Hi, I am wondering if there is a roadmap about Vray RT gpu improvements. In general are u guyz going towards gpu direction more than cpu in the future? I am asking this after testing many gpu engines and while i love the speed, i always come back to vray for its flexibility. I been using RT more and more lately and i think its ok, but is not reliable for production yet to my eyes.
I 'd love to see a final steady version with all features in RT gpu, some more responsive real time feedback, some real time tonemapping etc etc.
Thanks heaps

We will have a number of improvements in the upcoming SP, including support for light directionality, shadow catcher, greatly reduced VRAM usage for textures, ability to pick objects and materials in the V-Ray frame buffer, selecting focus points for DOF in the frame buffer and others.

Best regards,
Vlado

Add fog and aerial in there and i ll cry haha. Thanks Vlado!

Any ETA on Volumegrid for GPU? That would make a lot of people really happy

I hope to have it in V-Ray 3.6 next spring.

All sounds great! Shadow catcher you mean some matte or something else?

Yes, I mean matte/shadow functionality.

What I really miss from Modo preview in VFB is the ability to display the mapping of certain channels. So for example I have noise on a reflection channel, I'm totally blind to how the noise looks like. In Maya/3dsmax you have a stack preview where you can see the state of an output in pre rendered in image. Such a thing sadly not exist in Modo.

But Modo has another, even more useful feature, you can turn your preview viewport to display all output channels in your scene (without defining a render output). I mean not the rendered output of the effect, but actual just the mapping of the channel values. That feature saved me a lot time, especially with bump mapping and gradients. In V-Ray instead I feel like blind on one eye.

Also I think VFB could be enhanced by an option that controls the outputs that are just visible in VFB and those which get output to file. For example you use EXR layered output and have a denoiser and some effects in your scene. The user might just want RGB, Alpha and the RGB denoise to be saved.. but instead get a very bloated file output, containing layers that are just useless.

If I understand you correctly, you want to be able to see each texture without any shading and effects, just in flat colors to see how it looks mapped onto the object? This is something that is really helpful indeed. I know that Blender has it too but there's no easy way to do the same in Max. A workaround is to use the texmapPreview script from Soulburnscripts. A bit clunky but does the trick. I also posted a thread about this some time ago.
