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.
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.
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…
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?
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.
