Greetings dear 3D artists!

According to the tutorial on "Ryan King Art" YouTube channel called "Procedural Marble Material (Blender Tutorial)" I am trying to create a marble material. The second material, Dark Marble, produces a pink texture error. This happens when connected to the Height input of the BUMP node. When connected to the Normal input, everything draws well. What can I do in this situation? Blender version 2.93.

P.S. I have already created a lot of materials by YouTube tutorials. I've had a lot of similar errors. Before, I didn’t understand what was happening. Now I see that the combination of the BUMP node and the Normal input on the Principled BSDF node gives a pink error when using the Height input on the BUMP node. This combination of nodes is very often used by bloggers. And everything works well for them. Maybe I have a weak computer for these operations? Here are the parameters of my PC.

Model: Acer Aspire F 15.

CPU: Intel Core i5-7200U 2.5GHz.

Video: NVIDIA GeForce 940MX with 2GB dedicated VRAM.

Memory: 8GB DDR4.

  • $\begingroup$ can you share your file with us? Because that shouldn't happen and I don't think that your HW is the issue, oh you just added your file, going to check it $\endgroup$

    $\begingroup$ Okay it works completely fine on my hardware... It shows as it is supposed to be when you put it into Height input (btw Normal input should give you bad normals because it expects blue/purple normal map, not black and white texture) $\endgroup$

    $\begingroup$ I am not entirely sure, If I cannot replicate your problem there is no way for me to find out what may be wrong, you definitely have minimal requirement to run Blender which is 1GB GPU and I was able to find benchmarks with your card... I would suggest you to try different versions of Blender (this was 2.93.5?) Try some from 2.8, update your drivers if they are not up to date and try to check if it works in other situations or not $\endgroup$

    $\begingroup$ OK. After installing the new nVidia driver, everything began to work. Thanks for the help. Can you give your answer to close the question? $\endgroup$ Nov 25, 2021 at 16:25
