No Sun on GPU

V-Ray V-Ray GPU Issues
1

If i use Sun and Sky i cant see the Sun on GPU.
Is that a known limitation?

Thanks for the report. This is a known issue, which our developers are informed about and it is on their to-do lists. I’ll bump its priority additionally.

Hi, any progress on this?

Looks like that there is a same limitation on V-Ray 5 GPU.

disappointing to see this bug persisting, especially with the higher pricing.

Just to inform you, we are looking into the matter.

For those with access, V-Ray Sun disc would be visible starting with tomorrow’s nightly.
After some more testing, we will enable it in the stable nightlies as well.

Thank you for the update! :slight_smile:

Hi,
Do you have any news on the Sun visibility for VRay GPU ?

10

I am also very interested in this. And also the “affect specular” checkbox which doesn’t work on Vray GPU. Thanks

@gaara_the_nightmare Read the post from @a7az0th above.
@flaviuscristea Yes, direct lights’ affect diffuse and affect specular parameters are not yet supported in V-Ray GPU. We already have an improvement request logged (internal bug-tracker id: VGPU-3998), which I’ll bump additionally.

Hi,
@hermit.crab yes I’ve already read the comment of @a7az0th and the sun visibility is still not working in GPU on vray_adv_50006_max2020_x64_30361.
Did I miss something ?

Thanks :slight_smile:

I see also so sun here on GPU on Maya.

14

@gaara_the_nightmare What @a7az0th meant was the nightly nightlies. There should be a stable build available for both 3ds Max and Maya from today where the sun is visible (the horizon blend is yet to be implemented).

15

Thanks it does work fine now.!

Hi @hermit.crab , thanks for the info.

I just tried the version vray_adv_50006_max2020_x64_30367 and I can see two problems.
First is the blend in the horizon, but you already mentioned it earlier that it’s not working.
The second problem is more important to me, the sun is not visible yet in the reflections of the objects.

This isn’t in the release notes. Anything else that has been fixed but not documented in the notes (full support for ForestColor map, TyFlow UVW, broken UVWrandomizer + displacement…)?

Hello? Anyone here?

Hello aleksandar.hadzhiev
I am also trying to get the sun disc to render on vray GPU (3DsMax) and no luck. I am using the July 50005 latest officiaL build (end July). Can you please provide link to the nightly build that - if I am reading this correct here - does have the sun disc GPU issue fixed?

Thank you
Martin

The sun disc on V-Ray GPU is currently available only in the stable nightly builds which you can download here.
