Alpha Trees - Render massive forests, fast

I’ll set it up again.
but had not changed anything in the path.

I had opened the scene in K-cycles where the error occurred,

Hmm, that’s very odd, does it work when you open it in normal Blender again?
I don’t have K-Cycles, so I don’t know if that would affect it…

have checked the path in the Prefernces,
then it worked again ,
did not change anything today.

very strange

Reopened Blender, loaded the scene,
textures not there,

path selected with Ctrl c

has already caused that the textures are there again

Hmm, ok, I think this probably has something to do with how the previews are cached, when you update the path, it updates the cache, and it all works again. I’ll try and replicate it and find a fix. Thanks for reporting that, that’s very useful!

Ok, I didn’t manage to replicate the error you had, but I have a fair idea what’s causing it, so I’ve uploaded a new version that should fix it :crossed_fingers:.
As a side note though, investigating this bug also made me find another one, which is now also fixed. So overall, that was a good thing to look at!

Nice that it became a successful double solution.

Alpha Trees 2.0 has been released!

Alpha Trees header

It’s taken quite a lot longer than expected, but I think it was worth it to complete the update with all features.

Improvements:

  • Moved entire system to geometry nodes for Blender 3.0.
  • Added 133 new trees, increasing the total amount from 15 to 148!
  • Added a powerful system for controlling distribution using layers.
  • Icons now load instantly instead of taking up to 40s for the full library.
  • Icons are now also higher resolution.
  • Added tree search to make it easier to use large libraries.
  • Camera clipping and targeting is now fully automatic.
  • Completely rewrote the documentation.
  • Restructured the entire addon to be easier to develop.
  • Added ability to fade out trees when they get too close to the camera.

+ a lot of bug fixing and head scratching

Trailer:

The price has also now gone up from $35 to $45, but if you get it now, you can use code “alpha20” to get a 20% discount (Only valid till 22 Jan)

It’s been a bit of a marathon, so I’ll be taking a bit of a break from development for a while (Aside from bug fixing etc.), but after that, here are some things I’d like to do in the future (in order of soonest to farthest away):

  • Add better support to Weight Layers and mesh it a bit better with Alpha Trees
  • Redo the entire generation system to also use geometry nodes, and some new techniques I’ve thought of for more reliable and higher quality trees.
  • Add support for types of Alpha other than trees (heathenous I know :exploding_head:). Think grass, rocks, clouds/mist, buildings etc.

And of course, thanks to all the people who used the beta and weeded out all the bugs I managed to leave in! @walt1 @marcatore @giacometti777 @Mash3d + others.

Congratulations! “Add support for types of Alpha other than trees” How does the alpha generator work with buildings etc?

Hi. Will these features be part of Alpha Trees 2.x or will they be in 3.0 (meaning: the user will have to pay more $$ to get them)?

Well, that’s all a plan for the future, so it’s not completely fleshed out yet, but it should be fairly simple, as the shader is probably quite similar to the tree shader but without the translucency…
The general process would be the same, but with some modified steps to make buildings look better.

@xan2622 I’m not entirely sure at them moment since it’s probably a fair way in the future, however, all users who have already bought it will definitely get a free upgrade to 3.0 when it comes out, just like with 2.0

Woah, that’s really nice!
I’m surprised how good they look that close up, great work!

Just a quick update to say that I’ve added a new “Lite” version to the Blender Market store.
This version has all the same features as the normal aka “Pro” version, except in only has 50 trees instead of 150, and it doesn’t have access to automatic scattering or camera culling.

The price of the lite version is $25 versus $45 for the full version.

My reasoning is that $45 can be a bit of an off-putting price for people with poor hardware, who would probably find Alpha Trees the most useful.

Also, anyone who has already bought the addon will automatically be given the “pro” version.
