Maxwell Render | Official public forum

Hi,

Firstly, let me say that I love Maxwell 4, the GPU is super quick for me. I am really looking forward to seeing it progress.

I have been setting up a scene with emitters at the windows as per the photographic techniques video. In that it says to set up a vacuum material, i.e. Transmittance white, ND 1. This does not seem to work on GPU. Is there another way of doing this or do I need to render CPU?

This is Max 2017 btw.

Another thing is that I have found that Maxwell 3 renders a lot faster than Maxwell 4 in CPU. Hopefully this will be resolved in later releases.

Keep up the good work

Cheers

Ok, after reading the logs it is not currently supported... Hopefully soon it will be

Vacuum or ghost material is (or should be) partially supported on GPU. I am the one doing that. Should be ghost for camera, and working to making it ghost for light rays.

Hi Luis

Thanks for the reply. I have tried it on GPU and then switched to CPU. It works fine on CPU but no sunlight comes through on GPU. I am guessing it is that part that is not working yet?

Cheers

You're right Neil. We will fix it soon.
