The contour lines plugin works very fine, but I don't find suitable parameters for my scene. I guess the reason is my use of the BiDir render engine that I need for the tracking of the laser beams light path. The BiDir engine does only support a few AOV's and not the irradiance.B.Y.O.B. wrote: ↑Fri Aug 24, 2018 10:32 pm If you use Blender and the new BlendLuxCore addon, you can just enable the contour lines plugin in the imagepipeline settings and start the render (it even works in viewport render).... it is a bit hard to find the right values for the different parameters of the contour lines.
However, I found a bypass calculating the brightness of the rgb colour using the following compositor nodes:
The result is quite good: So, the colouring works, but the render result (.png) is not so sensitive to give me precise brightness.
I think the result would be very precise, when I could work with the basic irradiance.
Is there any way, to get the irradiance for the BiDir engine?
