Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Texture pixelated when painting onto terrain

Hi, I am having an issue that whenever I paint onto the terrain the texture become pixelated. I am using simple colours (no detail in the textures![alt text][1]). It looks very bad and I just want it to fade out, not just stop.

Hey DW123, you need to increase the falloff on your brush. 1 means max blending, 0 is no falloff so you get very solid lines like what you are seeing now.

Hope this helps, Tom.

Could you post your material and we can see if it's something in there.

That is all the material is made of.

I just had a little play around and I got some pixalation also.

Try to fill your entire landscape with your grass layer first (Change the brush to component). Once that's done, try to paint your layers as normal.

I'm not really great with in depth options, how would I change the brush to a component?

avatar image Illarvan May 01 '17 at 06:55 PM

You can change it like this :)

I painted the whole landscape with the brush as a component, then painted as a circle brush.It still looks pixelated!

I think it might be the height part (where your alpha is plugged in).

Try switching to weight blending instead.

Still nothing :/ I even tried changing the Preview Weight to 0.

I can't see anything wrong with what you've posted. Try with a fresh landscape, then fill with grass and then try painting.

avatar image DW123 May 01 '17 at 08:12 PM

Didn't help, still pixelated. I did find that if I kept the Layers as a LB Height Blend and disconnected the Alpha from the Height in the Layer Blend node that it does work good enough (in a weird way), it's like using the smudge tool in photoshop. I'll stay with that, until there is a way to fix this.

If it feels like it's smudging turn up the weight to 1 on all layers.
