Tesselation BluePrint

NunoMartins · April 9, 2015, 10:46pm

Hi Guys, what am i doing wrong?

The Tessellation wont work. Why?

Help Please

Sparven · April 9, 2015, 10:54pm

Hi,

Sadly I can’t help you with this, but shouldn’t this be moved to a more appropriate section of the forum? As it is a question regarding materials if I’m not totally lost right now

Welcome to the forums btw!

'I’ve tried so many times, i can’t.

Quick question, are you running on a Mac or windows system? If a mac, tessellation will not work as its a directX11 only feature.

Windows 7, directx 11

Can you copy/paste your blueprint here: http://blueprintue.com/

Yes.

O.o

I copy/pasted that into the link I provided: http://blueprintue.com/view/9nJLTwWm/, and none of the pins are connected. Once I get home tonight I’ll look into it a bit more to give a bit more infographics on how to set it up.

I wanted to check something anyways relating to tessellation anyways.

SaviorNT · April 12, 2015, 8:09pm

Mmm, looks like even for me the pastebin is a bit broken, at least for material blueprints. Such is my bank account, always broke

After copy’ing and pasting yours into mine, it looks like the material is set up correctly. So there are 2 other things that I can think of:

Project Settings -> Platforms -> Windows -> DirectX 11 (SM5) = Checked
Final Material Details -> Tessellation -> D3D11Tessellation Mode = PN Triangles
Final Material Details -> Tessellation -> Crack Free Displacement = Checked
Final Material Details -> Tessellation -> Adaptive Tessellation = Checked

NunoMartins · April 12, 2015, 9:28pm

yes, everything checked.

i think i have a problem with my directx, i will try another computer, if it works, i will format mine and try again.

Arnage · April 13, 2015, 12:39pm

The direct x version listed on the first page of dxdiag is not particularly relevant as it only indicates the software version, not the version your hardware supports. Additionally, that page doesn’t even list the GPU, so it is impossible to determine whether tessellation should work on your system based on that information.

The actually relevant info is on the Display tab. Could you post that one instead?

kirk.clawson · April 13, 2015, 3:53pm

Based on the laptop model, it’s apparently using the built-in Intel HD Graphics, which for that processor, is only DirectX 10.1 / SM4 capable. Tesselation requires SM5 / DX11.

illYay · April 13, 2015, 10:02pm

Really? OpenGL 4 should be able to do tessellation as well.

kirk.clawson · April 13, 2015, 11:12pm

OpenGL 4, yes. But not DX10 (The SM 4 refers to Shader Model 4 - a Direct X Specification), and I don’t believe UE will use Open GL on Windows, even if it’s installed.

illYay · April 14, 2015, 12:49am

Oh I was referring to the comment about it not working on Mac.

kirk.clawson · April 14, 2015, 1:41pm

Gotcha. Sorry for the confusion.

NunoMartins · April 15, 2015, 1:03am

This is the right answer, my hd graphic is not good enough. i’ve made a test, based on what you say, diferent PC, worst HD graphic, won’t work, Diferent pc, Better Graphic work just fine.

Thanks!!!

I “just” have to purchase a better computer!!!

SaviorNT · April 16, 2015, 3:49am

Thanks for the answer. I was kind of wondering about the graphics card as well. My suggestion would be to get an Asus ROG laptop with a dedicated graphics card and no intel graphics. It will serve you in the long run if you ever decide to experiment in the VR space.

Be forewarned though, they’re not cheap at around $2000 USD or so.
