Maya Fluids temperature

[tinoxps]

Hi everyone,

I am new to vray and I am trying to do a rocket launch scene. For that I am using vray 3.6 and maya fluids.

I manage to render the fluid adding the attribute "Vray fluid render ..." and using the phoenix fd material.

I can see the smoke very fine, but i cannot manage to get to see the heat i configured with the emitted temperature. What should i set up to see the fire coming out and then the smokescreen?

btw i tested already the same density and temperature configuration in arnold, and there i can see the heat. I did this to check if i was doing something wrong.

If anyone can help, would be very nice.

Cheers
Tino

Hello,
Can you send us the scene so we can check it out?

Thank you,

Hi georgi,

hiere is the scene, I hope you can help me display the emitted fire.

Hey,
I have examined your scene and the solution is quite simple. It's just that you're using a V-Ray camera with Exposure correction enabled. This makes the fire of the rocket almost invisible as it's not very bright.
Just disable the Exposure correction in the V-Ray camera and lower down the intensity of your lighting. I have set the VRaySky to 0.05 Intensity and adjusted the Input bias of the Incandescence for the Fluid container to 0.870.
Here is the result. Hope this helps.

just another small question about the topic. If i manage to export the maya fuild as a VDB, then reimport it and use a VrayVolumeGrifMtl, can I use GPU rendering?

[georgi.zhekov]

Hey,
You will be able to render VDB files on the GPU in the next major release of V-Ray for Maya, until then you can still render them in CPU mode. Unfortunately I can't tell you when this will happen though.

ok thanks for the info
