Revit- Vray-Vantage

[gode_abuzz]

Hello,

I have a lot of problems with Vantage and Revit.

Indeed, for an interior animation, I have a lot of flickering problems in terms of shadows and light. I also have problems with textures disappearing or ghosting elements appearing during animation.

Do you have any idea of these problems?

I save directly in .mp4

Thanks a lot for your help.

I can send the video.

Hi Tsvetomira,

do you have some news for me?

I redid other scenes and other settings and each time I have problems with textures disappearing and reappearing and also flickering with the areas of light.
Surprisingly, if I render twice with the same settings, the same problems occur at different times. Kind of like it was random.

Thank you very much for your precious help.

Hi Vincent,

From the video you sent, the splotches are caused by the denoiser( and probably by the Reduce flickering option) How many samples did you use to render the scene? The textures disappearing could be caused by the "Enable dynamic textures" option (in Render tab>Advanced). Can you please render at a higher sample value, disable both "Enable dynamic textures" and "Reduce flickering" (you can also try increasing the Light cache samples in File>Advanced scene settings... to around 1500-2000 and increase Retrace threshold to 3)? Please write back what was the result.

Best regards,
Alexander

Hello Alexander,
I put the parameters that you indicated to me and the result is magnificent, thank you very much!
On the other hand, as soon as I add lights inside, I have vibrations in the lights and shadows projected. I think I need to adjust a setting on artificial lights, right?
Thanks for your help, it's really great!

Hi Vincent,

Can you please send a video of those "vibrations in the lights and shadows projected"?Be cause I can't think of anything else that you have to do.

Best regards,
Alexander
