Can't render the background image from an Environment Light with openGL Oct. 23, 2018, 5:01 p.m.

Hi guys,

How is it possible to render an Environment Map (as background image) from an Environment Light with the openGL ROP ?

For some reasons, I'm not able to get the background image visible in my render. I only get the lighting on my object, but not the background image. The background remains black.

In the Environment Light :
- Enable Light in Viewport is ON
- Render Light Geometry is ON

In the camera :
- Enable Background is ON

Exporting as .exr and .jpg and no difference

Thanks in advance for any help.

How a Flip sim can affect a Pyro sim | Fluid Density + velocity Aug. 12, 2017, 8:08 p.m.

Hi guys

I'm wondering how a Flip simulation can affect the behaviour of a Pyro/Smoke simulation. Do you have any solution ? (basic file attached to this thread)

Actually, I would like to create an underwater smoke simulation and that's why I was trying to affect the motion of the smoke by the Flip water density.

In the following example [] the smoke is affected by an air density field.
In my case I would like that the smoke will be affected by a “water field” to create and underwater behaviour based on water density and velocity.

I hope it's clear enough.

Thanks for your help

Thank you very much for your reply Edward, I understand what you mean.

The problem was in Krakatoa, so I have add a Negative node to my Normal attributs with the Magma Flow and now the rendering is correct.
