Title: [Solved] What am I doing wrong with Tonemap Control Texmap?
Post by: Giovanni Stengel on 2023-06-13, 18:57:11: I've tried all the combinations, but when I change the tone mapping, the environment keeps changing along with the rest. I have already tried restarting the interactive render.
This is just a test but I have a job to finish and I don't know how to do it! Thank you very much!

Post by: TomG on 2023-06-13, 19:17:01: You have to feed the environment bitmap into a Corona Tonemap Control and then place that Tonemap Control into your environment slot. In the Tonemap Control you can disable whether it is affected by various aspects of the tone mapping (and it does then require a restart to IR / Rendering to take effect if you make any tone mapping changes :) )

Post by: Giovanni Stengel on 2023-06-13, 19:51:28: Dear TomG, I have solved it! I did some testing and the problem lies in a little "bug" in Corona. In order to get the tone control to work I have to remove and then put the bitmap back in otherwise Corona won't make it effective.
Thank you!

Post by: Giovanni Stengel on 2023-06-14, 11:59:10: @maru I tried that multiple times and on multiple files. It wasn't working.

Is there any way to see tone mapping changes in real time using tone map control? Even just in the VFB window or other ways?

The CoronaTonemapControl map works as expected. Unfortunately, after changing the tone mapping settings (or exposure if you have it unchecked in TonemapControl map) you need to restart the IR to see the correct results - the map in TonemapControl not effected by tone mapping.

Post by: Giovanni Stengel on 2023-07-04, 16:44:07: Dear Aram, as I said that was not the point. To make it working I have to unplug and re-connect the material.

Post by: Aram Avetisyan on 2023-07-04, 18:09:09: Dear Giovanni,

That is exactly as if you were refreshing/restarting the render. I think we refer to the same thing :)

Post by: Giovanni Stengel on 2023-07-04, 19:26:58: Hi Aram! If I restart/refresh the render in that situation the problem remain. If you ,as support, need this info I can check again.
