fxaa/msaa does not work any more

Looks like fxaa/msaa doesnt work in last version.

Both msaa and fxaa work for me. I assume you have another graphical glitch because anti aliasing can not cause or fix wide spaces. I try to reconstruct your scene to find and fix the error.

Look at the edges of trees (texture with alpha). One — old engine, another — new one. Both: msaa = 0, fxaa = true. At first screenshot edges are affected by AA, but not at second one. And the settings are the same, only the version of 3DreamEngine differs.

I forgot to tell: I readded alpha tag of materials. Why? The engine needs to know how to render a material. In previous version I just rendered both variants, which is a massive waste of performance. I updated the readme. Section alpha. In your case you have default 0, which only renders solid parts. Semi transparent color is disabled. So your leave/foliage materials need alpha = 1, which uses both passes. While setting this manually is surely annoying, its necessary.

And what is the default alpha, if it is not set in mat? The main problem in in tress (both variants are good), but in spaces between tiles. So, I can add alpha to them, bat can it help? Looks like alpha should be 0 for their materials, and if this is default value… Looks like this issue duplicates #22. But it's harder in new version. The spaces are connected somehow with alpha blend mode: the only mode works fine with them is «dither» one. But it has problems with textures which have alpha-channel. And in old version of the engine it was possible to use «average» or «alpha», and no spaces. Looks like AA means nothing for these spaces…

Default is 0 (no alpha at all, fastest), 1 would restore the look of the old version. Or at least it should. But 0 should be fine since there is no semi transparent pixels. By just looking at the screenshots I can not explain the results, nor I was able to reconstruct it myself. It would be far easier for me if I had (read) access to your project.

2 demos. demo1 — old version of 3DreamEngine, demo2 — new one. Code, models, textures — everything is the same, except 3DreamEngine's directory. And the picture differs…

Thanks, I found the problem. Your PKM file contains a few pixel on the top left which are not alpha 255 (slightly transparent). You can fix this yourself (its not a big deal but technically wrong), but I will increase the threshold of the 3D engine anyways, so the next commit will fix this too.

EDIT: no, threshold is correct, see next post

True. Was confused by different results of renderer and haven't noticed this texture's bag.

When using disabled (you use disable, typo!) as blend mode it ignores alpha. Works fine for your project if you never use semi transparent pixels. When using alpha you need to tell the engine that the material of the road contains transparency (but I suggest removing those pixels instead)
