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"

Material gets invisible through opacity

Since 4.3.0 there is a little bug, I guess. Ever when I try to use a textures alpha for the materials opacity the whole mesh gets just invisible, even though I can see it in the material editor. In 4.2.1 it worked just fine. Any suggestions?

Info: You can't see it in the material editor in the screenshots because it is distance based. You can't see it if you are close to it. If you want to see the pictures better, download them or zoom in the page, they are high res.

The prove that there are objects and the code of the material. alt text

Hey Skullwing -

I think it was something about Imageshack not wanting to display them via a link. Looking through your images now, I don't see any immediate problems. Have you updated the texture at all recently? Take a look at the Alpha channel in the Texture Editor to see if its showing correctly there, upload a screenshot if you can.

Thank You

I didn't change anything, I just ported it to 4.3 and then ... nothing to see anymore. I already checked the texture editor and everything is like it always was...

Hey Skullwing -

I am going to try to rebuild your material in 4.2 and then convert to a 4.3 project. Let me know exactly how you converted your project, was it a open a copy or a convert in place? Also, you mentioned that the planes are generated in C++, are the materials assigned in the same code or are you applying it through the editor or blueprints?

Thank You -

I just opend the 4.2 project in the 4.3 version of the engine (convert in place). The meshes are cubes without top and bottom and placed via the foliage system. The material is added in the mesh editor on the cube.

I got the problem, the coordinate index of the texCoord was set to 1.
