Blender 3.1: the new beta seems to solve the problem related to the direct Cycles rendering of the flares. This new is epic! We are modifying all the shaders to be ready ASAP.

Finally we succeed: now it’s possible to create shaders that works directly in Cycles (it seems that Blender 3.1 solves the issues that we were experiencing). We’ll have to work hard to redesign all the shaders, but we hope to be ready in a couple of months. Each user will be able to download this upgrade for free.
