Backward Compatibility
With regard to a workflow for getting Unreal editor assets (Bush Gen02 01) into previous engine 4 versions, you must have 4.26 on your system.
- Double Click on the Bushes Gen02 01 project to open it, or any project you want to transfer to a lesser version engine.
- Navigate to the Mesh folder.
- Select the first bush mesh, then holding the shift key, select the last bush mesh. All meshes should now be selected.
- Right Click over any of the selected files and choose ‘Asset Actions’, then ‘Bulk Export’.
- Choose a Folder in the project of your earlier version engine, click ‘Select Folder’.
- In the FBX export window, click Export All.
- All the meshes and materials with textures will now be created in that selected folder.
- Open each material that has masks (leaves and flowers) and select Blend Mode as Masked, connect the A channel of the Texture to the Opacity Mask node of the Material.
- Check the Two Sided box in the Material.
That just leaves you to drag and drop the bush meshes into your scene. Make sure each bush mesh is set to Stationary before you build the Lighting, otherwise you will get errors.
I got this workflow transferring assets from 4.26 into 4.23
NOTE: I have not tried this method with Blueprints, Scripts etc.
Any issues, post them here and I will do my best to assist you.
