PNG does have an alpha channel (or at least the capability to have one). Your most recent image looks quite good to me...

You can actually create one in irfanview when saving .png It prompts to select the transparent colour. I've used it a bit.

I make my own textures (gathering branches and photographing them in front of a white board),

First, the image seems fine. Interestingly , I use a black background for the same purpose

In Photoshop I don't see an alpha layer in the png's I made, so I still wonder why I need to tick that box in TG for it to work.
Or whether it's wise to make the alpha layer. In the latter case, the file is just as big as the tif, so I might as well stick to that. Not really important, though, it works.

Here's my setup (I just had this white board). Never mind the title, it's not a birch branch.

The "use alpha" checkbox affects how it interprets the file you put into the opacity slot (whether to use the RGB as opacity or the alpha channel as opacity). Is that where your PNG is?

Yes, it is. See screendumps. But in PS there's only the RGB layers, no alpha. And I would have expected the transparent PNG in the color tab to be sufficient, but it's not apparently.

[Matt]

There must be an alpha channel in that image, otherwise you wouldn't be able to get a clean edge from just the RGB information that I can see in the screenshot (or maybe you could, but it would be inverted anyway). So, whatever Photoshop is telling you isn't the whole story.

TG's image preview also says it's only RGB, but it must be getting that matte from somewhere.

Have you had a look at it in Irfanview...sometimes it will show stuff PS won't but this is most curious.

[Dune]

I'll check it out, or zip the file for you to scrutinize.

feel free...I have time....lots of time, heh heh heh

In the meantime... lessened the number of leaves on the juniperus, so they get more light inside.

Great.

I certainly see a visual improvement concerning how the light interacts with the vegetation.

smart idea...looking really good Ulco.
