Question - Code Replacement for d3d_set_shading?

[Lerner]

Hello there!

I am creating a 3D game and I need to disable the gouraud shading that is applied on my 3D models, to get flat shading.

The left model of this example picture illustrates what I want:

In Game Maker : Studio 1 I can set the "d3d_set_shading(smoothing)" smoothing parameter to false, but in GameMaker Studio 2 the function does not exist anymore.

How can I achieve the same effect with GameMaker Studio 2?

I'm not sure if there is a replacement, but you can try to make a project in 1.4 that uses the d3d_set_shading() function, then import it into GM:S2, and see what it tells you. Maybe they have some kind of workaround compatibility script?

I already have imported an old project to get the compatibility script, but the said script just contains a warning message.

There is not a replacement for this as it the implementation is down to shaders and how the pixel shader inputs are set up

Has anyone achieved this? I haven't touched shaders yet so I'm a bit disappointed.

This can be done when creating the model, just make the model with flat normals in your model editor.
It can alternatively be done when importing it into GM by converting the vertex buffer to a normal buffer, modifying the normals and convert back to vertex buffer. This is a bit more complicated.
My model tool lets you switch between smooth and flat normals.
