marc dion (marcclintdion) added a comment to T43835: strange cracks appear on model.

If behind the scenes, Blender were to move the entire scene using the inverse of the camera transform instead of moving the camera itself, then visible close-up models would never be far from the origin. Now round-off/precision errors would likely be mostly eliminated.
It's a huge job that would take an expert in the field (not me of course! :) It would have to appear to the end-user that nothing has changed so far as UI and navigation are concerned.

To add to what Yury included above, if the models use Weight Paint Groups to determine the values for width and segments then multiple objects with different settings can be joined together.

@Dalai Felinto (dfelinto) It looks like I can get away with saying "you're welcome" since no one else is subscribed yet(no one around to annoy with undue email notifications ;). I just wish I had noticed it earlier, I've been too busy to use Blender much since last winter, I just wanted to test the bevel node.

marc dion (marcclintdion) added a comment to T48583: Bevel Improvements.

I think what I'd like to see is a threshold that prevents close vertices from overlapping without blocking the movement of vertices that are far from each other. I suppose something like a weighting that diminishes the bevel effect for close vertices.
Something like in the following which shows how Edge-Slide has less impact on close vertices but a large influence on vertices with larger distances. I think this would have to be an option though since it would best suit organic or choppy shapes like rocks. It would likely be inappropriate for machined surfaces.

I tried 'tnear.patch' and it generates a pattern on the model surface that sort of looks like some kind of paper bump texture(the pattern is nice :). The model also becomes very dark when moved far away from the scene origin and away from the axis lines. It looks as if there is a point point nearby and with no scene AO.

marc dion (marcclintdion) added a comment to T41092: Very high memory usage for Cycles baking compared to ordinary renders.

Here's an image that shows the basic setup for a benchmark test I've setup. The image only shows 4 monkeys but the benchmark has 100 of them. Each monkey head has a Sub-D modifier at 2 iterations. There are 300 textures and 200 of them are 2048x2048 input textures. The other 100 are 1024x1024 and these are the textures being baked to. All of the bake-to textures should already be selected for every material.

that was CPU rendering. I built 2 versions. First I updated from GIT, then I built 1 from master and then I applied the patch and built again and named it D722. As I said, it may not even be the patch that's the problem. Whatever was happening yesterday did not happen today when I actually had a screen recording going so I could log the very noticeable RAM climbing.

There is something unstable but I'm not having an easy time reproducing the problem. Yesterday when I started the test scene, I ran it several times and the memory usage often seemed to climb but never return to the original level. Now it's looking more stable, maybe running it over and over was having a cumulative effect. I've tried to reproduce the same conditions but no luck. It seems pretty much the same as master for the 2 setups I tried-> low and medium loads.

I've been setting up some test scenes that have moderate to heavy loads but it's going to take a day or two for the one that has 100 models and 300 textures.

marc dion (marcclintdion) updated subscribers of T41669: Viewport selection is broken.

Holding down Alt-Shift when click-selecting should give you a popup menu list of everything that can be selected based on cursor position. Maybe this still works even when other methods fail.
