GLTF Import Export

Post Load Skel Binding Parent Dev script needs: params.SetTerminationFlag()

Code: Select all

	if(importedActorNames == "")

params.SetTerminationFlag()
	return;

Roger that, thanks.

The "final" fix is in. It can export actors that have more than 1 mesh.
The problem was that there are 2 types of skinning and the sdk was giving a bad piece of information with one type.
The fix was to get the skinning for the meshes via script and transfer that data over to the plugin.

I think there should be a new release this weekend.

The only difference between left and right is that the right image has the walls, floor and ceiling subdivided. This was giving me trouble while trying to work out the lights import and export values. You have to have more geometry on large flat surfaces to get good lighting.

Latest version is looking and working pretty good!
Love the Open File Location!
Here is a Female Avatar scene
90 frame animation moving the arms down and up
Also added Keyframes using the Eyes L & R morph moving the eyes left and back to looking straight ahead
Exported and then Imported
I used Bind Nodes and then Apply Morphs
Got an error

It looks like the morph animation needs some work.
With glTF all the mesh morphs are animated at the same time, like the tS matrix animates tx,ty,tz,yaw, roll, pitch etc all together, so either need to require all morphs for the mesh are animated or some way to add zeros to the gltf file morph animations for the non-animated morphs.

Already fixed one problem with the animation names, the actor has names like "head/Vertex morphs/P - Jaw". If it wasn't an actor it would just be "Vertex morphs/P - Jaw" without the need for the mesh name at the front. Without it the body and head morphs were getting mixed up.

After fixing that and adding animation keys to all the morphs for testing I discovered that the morphs aren't matching up. I got the morph animation to export, but instead of the animated eyes I got an animated mouth. So the plugin needs to do something to match up the morphs in the exported file.

I do not have very much experience with Morphs and I had a heck of a time just adding the Eyes Morph to the animation
At first, it was not even working, but I eventually I got it to work
It seems like it got baked into one of the AnimClips
It looks like it failed (error) on the body morphs, in with which I did not add to the animation

Wonder if I add another Clip just for the Eye Morph, it would have made a difference

Stil, if I do not Import the Morphs, the two clips have extra keyframes that make the arms drift, which is not in the original animation
Also, her bobbies move, which is not in the original animation

[clintonman]

Fixed plugin code and got the morph animation to export to the correct morph. The change was surprisingly small but it did take a while to figure it out. Also found that the morph animations were being exported for disabled clips and fixed that.
Last fix for morphs will be to default morph animation values to zero for non-animated morphs of the mesh. If cannot then it will be required to set key frames for all morphs. An all or nothing situation.

ABeautifulGame sample with full 2k textures

I decided to give the 4GB Patch someone mentioned in another thread a go on the Rosetta.exe file

Now the gltf importer will import the chess board sample without crashing. There was a fairly long delay before the model showed in the viewport.

Goes without saying, but use at your own risk.
