Vertex displacement performance unusable. What am I doing wr

[leave2]

I'm really struggling to understand how mixing displacements is viable using Vertex displacement, as in order to get any decent resolution, I have to pump the subdivisions up until the displacement alone is generating millions of polys.

Is there any plan to make texture displacements stackable? Modo did this brilliantly and seamless, with almost zero performance hit.

Alternatively, is there a way to stack displacements that doesn't cause huge performance hits?

Hi sorry, I didn't realise soeone had replied. That link doesn't work for me unfortunately.

I can handle not being able to mix displacements, to be honest, my main bugbear is that I can't figure out how to make Vertex Displacement useable.

I'm on a 3090, so I feel I have at least a relatively powerful machines, but even today, simply adding a single noise node to vertex displacement, and even at subdivision level 3, the triangles jump from 600k to 45 million. If I go lower subdivisions, the displacement has zero detail.

Is this how vertex displacement actually works? If so, does it mean it's just a terrible feature? I don't understand how it's even possible to use it without a supercomputer, I had to wait 12 minutes for the viewport to update.

Any help would be really appreciated, I'm fully willing to accept the high possibility that I'm simply doing it wrong

Thanks!

Hi mate, thank you for the response, what you say makes sense. I dropped by samples down to 8, and it has definitely made an improvement in responsiveness. The reason for using vertex displacement is because I need to create a texture that requires the noise node, and whenever I use it with a baking texture node, I get unsatisfactory results.

Thank you, though, dropping it down has made it usable, that's a huge relief. I really appreciate the help

Sorry, I have to come back and repeat that I am so grateful for your advice, it's made vertex displacements completely useable for me and has transformed how I'm building organic textures. You're amazing. Thank you!
