I guess I'm still using Blender from command line? It's like I just run "blender my_blend.blend -b -p my_script.py" It works in my local device but not remotely

Re: opencl device selection string has the wrong length, must be 3 instead of 1
I guess the scene was saved on a PC with 3 OpenCL devices, just go the the BlendLuxCore device panel, refresh the list and select your GPU :idea: Hi Dade, I met this exact problem, but in my case I'm trying to render through python script remotely, so I cannot open the Blender GUI to refresh the GP...

Re: Nonvisible spectrum
Hi Dade, the filter clamps all the wavelengths below ~700 nm, and our illumination is above 800 nm, so its actually not working in the visible range. Is this possible to be simulated? Not directly but it should be possible to workaround the problem: it is just a convection to interprete the 3 numbe...

Re: Nonvisible spectrum
How does the filter works exactly ? Are you still working only in the visible Spectrum ? If you filter just clamp the range wavelengths visible, you may need only to post process the final output of the rendering. I mean, for instance, if a filter clamp the wavelengths between 625–700nm (i.e. only ...

Nonvisible spectrum
Hi, In my application, we use near infrared illumination light source and monochrome camera with long pass filters (wavelength below red will be filtered out), and we are trying to simulate that. I noticed Luxcore can transfer spectrum into RGB and then saved as BW in the rendered result, but is it ...

Re: Questions about projectors (spotlight with image)
It is the light received by the surface, what the camera sees depends by other factors like the material and orientation of the seen surface. You need to multiply "c" for the dot product of the surface normal and shadow ray direction: this is the received light. Than you need to evaluate ...

Re: Questions about projectors (spotlight with image)
ProjectionLight::Illuminate() takes a point a return the amount of light received and the shadow ray to trace to know if the light sources is visible. Assuming the light source is always visible, you need to integrate the values of ProjectionLight::Illuminate() over the surface you want to examine....

Re: Questions about projectors (spotlight with image)
Yes, but over the complete projected area or on a point ? Anyway, it is math it is possible to derive from the model but to what porpoise ? For you it may may be just easier and to look at the values on the EXR output :idea: Over the complete projected area. I'm doing a projector simulation, and it...
