Description

System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 466.27

Blender Version
Broken: version: 3.0.0 Alpha, branch: temp-geometry-nodes-fields-prototype, commit date: 2021-08-10 17:09, hash: rBc920b83b8456
Worked: (newest version of Blender that worked as expected)

Short description of error
In the fields prototype, blender will crash when setting the axis and pivot to the same value. It does not matter if the node is connected to anything.

Exact steps for others to reproduce the error
Add a geometry nodes modifier to any mesh. Add an 'align rotation to vector' node. Set both the axis and pivot to 'X', 'Y', or 'Z'.

Thanks for the report. I can not reproduce on 3.0.0 (rB7d8c71e8003 and rB4c26bb02327f , 2021-08-09)

Please check again with daily builds: https://builder.blender.org/download/daily

Also Please provide the .blend file if crash happens on the latest 3.0.0 build.

Tested with the following node tree as described in the task:

First of all, I was referring to the experimental branch:
temp-geometry-nodes-fields-prototype

Second of all, the crash happens when the "Axis to align to the vector" and the "Pivot" are both set to the same axis.


(In the image, if I were to click LMB, blender would crash )

Hi, thanks for clarifying. I failed to notice the branch even though its clearly mentioned in task title and description.
I think the bugs from the experimental branches are not tracked on bug tracker.

the crash happens when the "Axis to align to the vector" and the "Pivot" are both set to the same axis.

Crash does not happen at least on master branch.

I think the bugs from the experimental branches are not tracked on bug tracker.

I did not know that, but I guess it makes sense. Would it then make more sense to directly message Jacques about the bug?

The prototype branch is no longer maintained. We started working on the actual fields implementation in a new branch today. Once that becomes a bit more mature we can accept bug reports.
