Maxwell Render | Official public forum

The Early Build v3.0.1.3 allows us to use low dynamic textures as IML maps.

I was happy to see this new ability and assumed this meant that we would be able to use JPG images in the 'Background' slot. I did a test render and got nothing but a black background even though the view port in Maxwell Studio was showing the background image correctly. I then raised the 'Intensity' to the maximum value of 1000 and did another test render. This time the background was visible but it was very dark when compared to the original JPG image.

I'm wondering if there is a bug or I'm just not getting something?

I'm sure there is a technical reason for this but I'm also wondering why the background image even needs an 'Intensity' slider or why it is affected by exposure levels? It would be great if there was an option to force the background to come out looking EXACTLY the same as the input image. I know I can render out an Alpha channel and apply a background image in Photoshop but I've had cases where I've had very fine high frequency perforations that the Alpha channel method just couldn't handle very well. When I try to remove the fringing with the 'Remove Black Matt' tool in Photoshop the problem became even worse.

We will check this, but the background already has a separate intensity setting which means you can either:

- raise the intensity of only the other channels to keep the background the same
- raise the camera exposure but then lower the intensity of the background to keep it the same

Yes this is the intensity value that I set to 1000 and the background was still coming out way too dark.

Raising the camera exposure isn't an option as it is currently set correctly for the rest of my scene.

yes it's too dark
