Stylized Trees with Blender and Unreal Engine 5 

Pontus Karlsson's the genius who came up with this method. And its around 2 year old.

@@ferozhossain3401 True.. I just took reference from multiple fellow youtubers.

Great.. thanks for adding that.

Yeah im stuck aswell on this part. :D

Looks like the UVs are in a 0-1 range for each face on the mesh. In Blender, you can select all faces and press 'U' then 'Reset' to map each to the UV bounds.

I used runtime virtual texturing for grass

Didn't understand the issue

Alpha transparency technique has been used since ages in games..it actually uses more calculation power in comparison to a fully colored texture.. however even basic graphics cards of today are powerful enough to handle it. I have created big enough scenes with alpha textures and they work fine. It depends on the scale of your project. You can also check the SHADER. COMPLEXITY in UE to validate your material's usability. Check this video of mine ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7pfcBaRcVOI.htmlsi=To69BBi1Ka1c1oYF

The same problem. Have you found a solution?

@@user-fj7sl3gn8h Unfortunately not, I have been experimenting with some different shapes in Blender to use for the leaves, but it is hard for me to get a dense and fluffy look. One shape that I have found gives an alright look is the following: align about 10 simple plane objects in a dome shape (half of a sphere) and make sure the planes overlap a bit at different angles (for fuller and fluffier look). To make branch less visible you can duplicate this and rotate it 180 degrees so you also have a bottom half, and/or duplicate it again and form a second layer floating a bit on top of the original. Then cover each branch with this. This does not give the best of looks and also still costs a lot of leaf images to produce. Let me know if you find something better^^

Same problem, if I find something I will tell you.

I FOUND THE SOLUTION BOYS, in the Leaves material graph, look at the "TransformVector" node. They have things that you can change. Be carefull at looking if you have the same settings as him.

@@ASTR0KARMA Thanks! The problem I get now is half of the leaves become smaller instead of bigger when increasing the scale

Yes, it is because of the light angle. Only way is to change the density of the leaves at certain places.

Ok nevermind found it . Mark Seam at UV tab in Edit Mode. :)

No need to change normals in blender.. It works fine in UE

I have the same issue, have you found a solution by any chance?

@@Tmarmoratus sadly no 😭 I got frustrated and downloaded one from the epic store

@@rampardos707 Thanks for your response, unfortunate. Haha nice, I'll have a look aswell. Im still trying to make different variants of leaf spheres in blender but I can't get a good result yet

@@Tmarmoratus you are very welcome! I really hope you can get do it, let me know if I can help you with anything else

⁠@@rampardos707@Tmarmoratus don’t know if you finally found the solution, I think I did with the help of All the Works. Check your transform vector nodes in the leaves material, It’s probably wrong like mine. The first one has to be « Camera Space to local space » and the second « local space to world space ». Hope it works, keep it up!

You can download buildify by Paveloliva for blender.

For grass and foliage, checkout my latest video. Water shown in this video is from the marketplace.

I have found out that this issue is caused of the second TransformVector Node in the LeavesMaterial

I am also having the same issue. the faces rotate when I increase the scale value. it flips sideways and does not look good were you able to fix yours?

@@monkeytheory4718 Unfortunately not, like you though I eventually realized it was the scaling. I've taken a pause on the trees in my environment at the moment, but if I find a solution to this I'll let you know. Let me know if you find anything!

I have the same issue...

that is a 2 vector value.. just press 2 on keyboard and click in material editor, or right click & search Constant2Vector

me too.

look for the transformVectore node in the leaf_mat, it looks that u have to change the " spaces ", i cant figure it out, and the combination in the video doesnt work for me

@@Inwardcrowd2210 you were right, the first transform vector is camera space to local space, and the second one was local space to world space, hope this works for you because your comment saved me :D

@@mddie10 If you have nanite enabled on the leaves, its that combination that you mentioned, if you dont have nanite enabled its (camera to instance and particle space) (instance and particle space to world space) hope it helps.

Maybe because of normals.. Try resetting normals

-Sorry- ignore me I hadn't reset all my UV's 🤦‍♂

Subdivision and skin, that's it. After applying the modifier, you can optimize the mesh.

@@ALLTHEWORKS11 thank you for replying! :) I'm not sure how you're changing the mesh. At 1:44 you're in edit mode and I can see that your tree mesh is now covered in vertices, which you have all selected... but how did you get those vertices to appear because using the skin and subdivision modifier does not create all those vertices.

​@@sharise4668I think you are getting confused in Applying the modifiers. So, when you see the modifiers in the tab, they are active & you can go to drop down of the modifier and click on apply. Then the modifier will be gone and the setting will be permanently applied to the mesh. In this case, when the modifier is active, the object doesn't have any faces. But when you apply the modifier, that converts it to a mesh. Those vertices are after applying the modifier.Check out this video for more details: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wmn2mdUYt60.htmlsi=4VtdI44QSGi-2kVy

@@ALLTHEWORKS11 ohh! i completely forgot that actually APPLYING the modifiers was it's own thing! haha my bad :) thanks again for responding!

Press and hold 2 and click anywhere in the editor window

@@ALLTHEWORKS11 Thank you! I thought so, It looks different in my version of Unreal Engine, but is exactly the same :)

For that you can check Shader complexity in optimization view mode.. I checked it was all green.

@@ALLTHEWORKS11 Sorry. I'm kind of new in Unreal. So I don't know if there's a relation between vertices and shader complexity, but actually I am concerned about the number of vertices and triangles. Anyway if there are going to be any performance issues I will try to reduce their numbers and make some LOD-s because your trees are looking great. This solution for the leaves and flowers is looking lot better than just adding some planes.

@@csakegybolond264 As it is a Nanite mesh, UE handles polygons comfortably

@@ALLTHEWORKS11 I've read about it in the documentation that we should apply nanite to every mesh. However, at moving foliage with a lot of polygons (for example 20k grass mesh) I experience a big performance drop while nanite is applied compared to the performance without nanite. Plus I've read other guys running into to the same problem with nanite. But I've heard it's very good in the case of static meshes without any movement. But I am not sure if only the textures doing the movement why nanite causes that drop since that is pretty cheap for the GPU. Maybe my 4gb GPU memory is not enough for nanite to work efficiently.

I made it with 5.1

@@ALLTHEWORKS11 yeah 5.3 is really bugged atm. So that was version being used. I did a field test and it is hit or miss for it to work with me and my team.

I have used UE 5.1 here.. Anyway, just check all the UE material nodes carefully.. It should work.

@@ALLTHEWORKS11 I used 5.1 too but the sheets are separated in the mash

@@Mastrechief Did you find a solution? I have the same issue
