Lukas Stockner (lukasstockner97) added a comment to D5799: Add support for Zstd compression for .blend files.

Update on the per-block compression: It works, but the compression ratio suffers from the small blocks - the file from above is now 544MB on level 3. In theory dictionaries could help here, but I'm not sure how to implement that practically.

Lukas Stockner (lukasstockner97) added a comment to D5769: Continuation of D3433 - Visible lights in cycles.

The invisible light in front of the background isn't a problem in Cycles - if you check the pixel values of the rendered image, you'll see that the lamp is actually there, but they also have an alpha of zero.
This is consistent with the lamps being transparent - after all, the point of transparent background is that you can composite it over your own background, and since the lamp is transparent, you're supposed to get both the background and the lamp.

Lukas Stockner (lukasstockner97) added a comment to T69745: Environment Importance Sampling gives too much noise.

The current code samples the CDF as a piecewise linear function, but the underlying PDF is piecewise constant since it's the derivative of the CDF.

Lukas Stockner (lukasstockner97) added a comment to T69745: Environment Importance Sampling gives too much noise.

In the past, I've considered tweaking the sampling algorithm to sample from a piecewise linear function instead of piecewise constant, but that would only help if the CDF map exactly aligns with the background image.

Memory spike shouldn't be too bad, even with the 1400 copies of the fairly complex shader it's only 10MB (and that's before the mesh and image sync).

Lukas Stockner (lukasstockner97) added a comment to D5376: Merge per-shader SVM nodes in the main update thread to avoid locking and resizing overhead.

Note that the merging step could also be done multithreaded by using atomic fetch_and_add to count the total nodes while getting the own per-thread offset, then allocating the memory in the main thread and then copying the nodes to the position from before in each thread. However, this would require some way of synchronizing the threads and I doubt that the additional complexity is worth it.

Lukas Stockner (lukasstockner97) closed T63708: Texture painting - Tools Tab - Brush Panel - Brush Colors in color picker are dull as Archived.

As far as I can tell, this issue is somewhat misleading - at first glance it appears to be a color management issue, but what actually happens is that enabling the Gradient option disables the Color Picker controls. Note that by toggling the Gradient checkbox, you can swap which of the two colors appears dull and that the Color Swap button changes along with the colors.
