Phil Stopford (philstopford) added a comment to T67594: Loading a scene file from 2.79 that isn't set to use Cycles or Eevee falls back to Eevee and can yield a crash for larger scenes.

i tried to give you a trick to mitigate eevee's fallback for large scene

disable the LoadUI option when opening the file

it work?

That overlooks the issue of Eevee crashing, though, which is my primary concern here and why I reported the issue. Silently crashing without any guidance to help the user seems like a bad thing. There's zero reason for the user to try 'load UI' when faced with a crash like this. Could the Eevee crash be caught and Workbench invoked as a basic level 'try not to die' mode?

@dark999 (dark999) : the test scene attached is small and focussed purely on illustrating the fallback to Eevee rather than Cycles. You won't see any errors from it (or at least should not do). For my larger scenes that were built in 2.79 (often with side-by-side configuration for Cycles and V-ray), loading those set for V-ray will fall back to Eevee in 2.80 rather than Cycles, and Eevee can't handle the amount of data (it seems).

No idea - screenshot attached, in case useful.

I do, but the scene is too large to make a practical reproduction case for the bug tracker. I had complaints for 'too large to be useful' before, so don't want to make that mistake again. The UI is blocked as Eevee is attempting to compile shaders, and I have no way to abort either that process or to change the renderer. The viewport is configured to whatever the fallback is in this case; I'm not actively requesting a render or a render preview in the viewport, and as the UI is blocked, it's impossible to change anyway.

The issue with Eevee, from the point of view of large scenes, is that it might simply fail due to the scene complexity, and it's unfortunate that its failure crashes the whole of blender. Falling back to something that isn't intimately tied with the GPU (where resources might well be constrained) seems like a safer strategy.

Phil Stopford (philstopford) added a comment to T56804: OSL bug? (interior shader).

OK. So here's a simpler example, which demonstrates the same problem. The only difference is, again, the negation of the values from the transform("object", P) call. This fixes the texture projection (for the most part). I think this is as simple as it can get.

Phil Stopford (philstopford) added a comment to T56247: Blender crashes with attached tiled EXR loaded (generated from attached PNG).

OK. I didn't realize that the time saving was that significant beyond throwing a sphere in; I'll bear that in mind for future reports and apologize for the aggravation caused.

Phil Stopford (philstopford) added a comment to T56247: Blender crashes with attached tiled EXR loaded (generated from attached PNG).

Again, I cannot save a blend file because blender instantly crashes when loading the EXR. I get that you're frustrated and consider me to be a contributor to your situation, but I'm genuinely not trying to piss you off here - blender crashes on loading the image. There is no window of opportunity to save a blend file.

Phil Stopford (philstopford) raised the priority of T56247: Blender crashes with attached tiled EXR loaded (generated from attached PNG) from Needs Information from User to Needs Triage by Developer.

I'm not sure what the objection is. Providing a blend file is not helpful here - the crash happens loading the EXR image in. I've supplied PNG and the resulting EXR file so that the crash can be better understood (PNG is not crashing, EXR is). Steps are provided. Release information and OS/graphics card information is provided.

Phil Stopford (philstopford) added a comment to T55610: Renaming a UV map breaks references in UV map nodes.

Indeed. I'm just offering additional background to help any decision from Brecht at this point :)

Phil Stopford (philstopford) added a comment to T55610: Renaming a UV map breaks references in UV map nodes.

For additional background, I ran into this following Brecht's advice on devtalk about how to workaround the UV map per object limitation; I went through renaming the UV maps on each object (prior to joining the meshes together) and all of the surfacing broke (since I'd made an explicit reference to each UV map in the surfacing). It was a fair bit of work to fix this up, so it felt like a bug (lack of notification or something)

Ah, that works. There's a different issue (multi-selection of objects, and 'add to group'). I'll file a separate ticket for this - I guess it's not related to this specific case.

Is this supposed to be resolved in the 2.79 code? I'm still seeing this behavior in the current nightly builds, so wanted to check

It's reporting as 2.79.3 in the header, so I thought this was 2.79b; I'll ask them why their labeling is misleading. Apologies for the noise.
