How to load and display a model at runtime

Hi,

I have a model in a well known 3d format (like obj/fbx/dae/3ds).
The model is fully baked and the meshes in the model have various kinds of textures(diffuse, height, emmissive etc.)

How can I load such a model and render in my game?
I knew that Xenko can use Assimp and load a 3d model but I could not find any sample code to render the loaded model.

Thanks in advance.

Why not import it with game studio and load it from the game content?

You can add the assimp dlls to your project …

Further you can investigate the methods in the dynamic libraries which are generated with the game. You can learn a great deal from just examining what is available to you there.

Hi,
I cannot do it as I am generating the model at runtime.

is it generative or load from file?

It is a generated model.

Then it’s pretty easy, you just create a MeshDraw class, assign your data and add it to a Model class. like here: https://doc.xenko.com/latest/en/manual/graphics/low-level-api/draw-vertices.html

or here: https://github.com/profan/XenkoByteSized/tree/master/XenkoByteSized/ProceduralMesh

The examples tonfilm provided are for immediate mode drawing.

I found there was a bit of a documentation gap in trying to understand how to load a retained-model into Stride3d, so that it handles drawing.

I wrote this sample, which loads a Wavefront OBJ file, at runtime, creates a model, and attaches it to an entity. This does not use immediate mode drawing, but instead sets up the buffers so Stride3d can draw it during it’s draw loop.

I also submitted a documentation update to: https://doc.xenko.com/latest/en/manual/scripts/create-a-model-from-code.html

Until it goes through, here is the relevant code snippit to manually add a single triangle to a MeshDraw:
