Hello!
Go to:
https://playground.babylonjs.com/#M7U9GS#18
Open the highlights material in NME:
Change this node’s target to Vertex:
There are some expected changes, no render. Change the target back to Fragment.
like this:
No render. Expected to have the highlights rendered.
Thank you!
Thank you! 
For the post process node material to work properly you need to use the CurrentScreen block as the texture block, not a regular Texture block:

That will ensure the texture lookups are always done in the fragment shader.
Hi!
Can we elaborate on this a bit please? I’m setting the texture by code and it works at first as you can see the highlights on the screenshot. When I change the target in nme to any other value and I change it back to the original one shouldn’t the result be the same and shouldn’t I see the highlights again? Thanks!
@Evgeni_Popov I guess I can repro what @roland said.
Basically if you change the target wrongly on a node → switching from fragment to vertex, currently there is a shader compilation error so then we can not recover the preview.
Even though the next compilation is sucessfull? I don’t know the implementation details just guessing that this should work. 
Ok, I found why it did not work when using a regular texture, here’s the fix:
If you set the target of UV scale to Vertex you will have to enable the Disable multiplying by level switch of the texture:
That’s because in Vertex mode the level property of the texture is used as a multiplicator for the lookup, and as the texture block has no texture the level ends up being 0.
Thank you!
