ASE Terrain shader with more than 4 splatmaps

[jojue]

Hi there,

I was setting up a custom terrain shader and wanted to us more than 4 splatmaps. So I added a AddPass shader to my terrain shader and set it up like in the Simple Terrain example. When I painted the 5th splatmap it appears in completely black.

So I went back to your Simple Terrain example and tried to paint a 5th splatmap to see if I made some errors, but it doesn't seem to work in the Simple Terrain example as well. It appears at a black texture, even though there is the SimpleTerrainAddPass added and the splatmap count is set to 8.

Is this a bug or are more than 4 splatmaps not supported by the ASE?

Thanks for your answer. I was searching the forums for a similar topic, but this thread wasn't shown for me.

I was setting my FirstPass and AddPass shader up like in your example, but if you open the SimpleTerrain example scene that comes with ASE and try to add a 5th texture you see that it will show up as a black texture and not the selected texture.

Is there something I've been missing?

I would like to attach a picture, but the board attachment quota has been reached.

Apologies for that, we're currently looking into the forum issues, you may use an external service such as imgur and the the insert image tag .

In any case, we've managed to track down the issue, it seems to be present on Unity 2018.3+ and it requires you to remove the Splat Count Tag in the SimpleTerrainFirstPass shader:



After doing so and compiling the shader, it should work as expected.
