or that it's something you could try to implement?
This, It would be a pre-processing utility, not really a rendering feature but it could be handy.

Re: Texture caching... amazing improvement in memory with Cycles, could be great in LuxCore!

That is LoD (level of details), it is different but, again, any mirror or glass can very easily mess the level of detail you have picked based only on camera distance. There are a couple of tricks you can use to alleviate that problem (by using not only the camera distance) and may be worth give it ...

Re: Texture caching... amazing improvement in memory with Cycles, could be great in LuxCore!

Regarding the Mip-Maps. ok, I understand, could be possible (just as an idea) to do some kind of pre-pass for such calcs and then upload to the GPU only the required mipmapped textures based on the camera being rendered? You can not predict where paths will bounce so it is not something you can do ...

Re: Texture caching... amazing improvement in memory with Cycles, could be great in LuxCore!

How out of core work on your side when GPU memory isn't enough ? on my side each time GPU couldn't render even out of core crash with lot of memory left on DDR4. It is all up to CUDA, it does it transparently for the application however I have some vague memory of some huge limit on Windows (it may...

Re: Texture caching... amazing improvement in memory with Cycles, could be great in LuxCore!

Oh, I was under the impression that the mipmaps could be generated on the fly by the GPU as they were needed, I thought it was an internal hardware based process, I didn't knew that the CPU needed to be involved in the process. Oh, no, the point is to not have the original (8K, etc.) images on the ...

Re: Persistent Cache not loaded

I have been enable to reproduce the issue i think: just precompute your cache and save somewhere and disable overwrite after. then press CTR+F12 to launch animation (make sure to choose a folder for frames ). By looking at the settings, you have enabled periodic updates: you must disable it or the ...

Re: Texture caching... amazing improvement in memory with Cycles, could be great in LuxCore!

However, what do you think about using MipMapping, something that is native for the GPU's and maybe can be easily handled? I think current Blender code only uses mip maps (not tiles too like Arnold). Anyway, the answer is no, when the GPU detect a missing mip map level, it has to: 1) stop the rende...

Re: PyLuxCoreTools - Segmentation Fault

Like I wrote before, you can try to track a stack trace with gdb but, by definition, a Python application can not throw a segmentation fault so you have something broken in your installation.

Re: 3D Modeling using SCULPT 4D on an emulated AMIGA 4000

:D Yes but sometimes it feels just like yesterday, now you don't have to cry anymore, with all the emulators and Pi available, you can do it again! No, thanks, rendering a mirror sphere over a (rigorously checked) plane with Sculpt4D was taking hours :mrgreen: P.S. anyway, on the Amiga 3000, I was ...
