Feeding Noise Texture Into Bump Map's Height Produces Error Pink Output

[hkunz]

Steps To Reproduce:

1. Open Blender 2.93, 3.0 or 3.1 on Windows 7
2. Go to Shader Editor
3. Add a Noise Texture node & a Bump Map node
4. Feed the Noise Texture's Color or Fac output into the Bump Map's Height input
5. Shift+CTRL+LMB on the Bump Map
6. Notice the output is pink

I was unable to follow your instructions exactly (probably due to my limited knowledge of Blender). Is what i did here correct ?

Shift+Click+LMB does nothing (other than selecting the node), so i connected the output of the Bump node to the Normal input and it seems to be working.

hey thank you so much for looking into this. yeah what u did was correct. are u on windows 7? i noticed you are running version 3.1.2

but the one i'm runnning was the latest you provided:

version: 3.1.0, branch: master (modified), commit date: 2022-03-08 18:16, hash: c77597cd0e15, type: build date: 2022-03-10, 15:53:22 platform: 'Windows-7-6.1.7601-SP1'

here is the error result: https://pasteall.org/pic/85c562452c3740f980fcefdac2baed34

PS: Ah sorry it was a typo. i meant CTRL+SHIFT+"Left Mouse Button (LMB)". doing that on a node will show you the result for that node. it's like debugging technique to see each node output.

is your 3.1.2 the newer version you compiled for windows 7?

[hkunz]

i tried the new version 3.1.2 from your release page https://github.com/nalexandru/BlenderCompat/releases and i still get a pink result as shown here https://pasteall.org/pic/85c562452c3740f980fcefdac2baed34 :( let me know if you are running on windows 7 as well coz that's where the problem occurs

[nalexandru]

Yes, i am running on Windows 7 SP1 with all updates (until Jan 2020, i don't have access to ESU).

I suspect it's a shader error. Start Blender with "blender_debug_gpu.cmd" instead of "blender.exe", repeat the operations and exit. After Blender closes, it will open a folder with two files, "blender_debug_output.txt" and "blender_system_info.txt". Please upload those 2 files.

That warning appears in my log too so i don't think it has anything to do with the issue. There is a shader compilation error on line 455 of blender_debug_output.txt: ERROR (gpu.shader): GPU_material_compile Linking:	Fragment info
Internal error: assembly compile error for fragment shader at offset 427508:
-- error message --
line 16649, column 1: error: too many instructions

I see from the system info that you have a GTX TITAN with driver version 344.11: renderer: 'GeForce GTX TITAN/PCIe/SSE2' vendor: 'NVIDIA Corporation' version: '4.4.0 NVIDIA 344.11'

Try updating the GPU driver to the latest version (and probably last) for Windows 7 which is 473.04 and can be found here: https://www.nvidia.com/en-gb/drivers/results/186161/

[hkunz]

yeah saw it now too

[hkunz]

oh nooo i get error when installing the update https://pasteall.org/pic/592d51cd44b14c2c932e4bf20eb86e15 but it finished installing hahahaha

Holy cow the problem is fixed!!! thank you sooo much!!!!!!

[hkunz]

thank you very much for your time and help i really appreciate it! and i did give you credits in my video on "how to install blender 3.1 on windows 7 :) https://www.youtube.com/watch?v=n3RGmnRTig8
