How to get depthTexture correctly?

21

I want to use it in my shader but I want to ensure it is correctly produced by visualizing it

Certainly what you want to do is possible. I donā€™t have time to find the JME example that renders depth textures in the HUD for you but they exist.

In the mean time, it seems like it would be a million times easier just to debug the values in your shader. Render the depth instead of rendering your normal color ā€œjust to seeā€, etcā€¦ Itā€™s also more reliable because itā€™s ā€œground truthā€ where as a secondary render is very likely to be one frame behind depending on how you hook it up.

Ok
Thank you
Iā€™ll try to use it in a Shader to see if it works
In meantime, if you could find a clue remember me

It works now.
It was a very stupid mistake, but I learnt a lot of things in the way.

It was in this code
reflectionCam.setFrustumPerspective(getCamera().getFov(), 1, 1.0f, 1000);

I was setting it as
reflectionCam.setFrustumPerspective(getCamera().getFov(), 1, 0.001f, 1000);

Near and Far Frustum is important in depth calculation
