Hey there!
Draw order problems can be quite common on transparent shaders with complex meshes.
Althought it depends on how the meshes and shader are setup, have you tried using the Extra Depth Pass parameters in the Output node?
Another solution would be through use of our
Shader Templates, by authoring a custom shader with separate passes for rendering front and back faces, allowing for much more control over the final effect. We offer a multipass sample, MultiPassDistortion, which provides a good example for this type of shader.
Please let us know if this helps!
