Render pipeline bad texture

[huitre39]

Hello I would like to understand how to display textures with renderPipeline

without renderPipeline i have a plane with a correct texture

i lost my texture why ?
and can i apply a reflection in my plane object (like a wet surface)

[serega-kkz]

I don’t think this will work with a card maker, since it doesn’t have tangents or other data. In addition, you need to adjust the material and observe the texture order.

In order not to dwell on this for too long, I suggest that you study the material settings and texture order in the examples you got with RP.

[huitre39]

ok but can I still have my texture (without the reflection)
or disable renderPipeline for this object only

in the examples it is always importing .bam models
otherwise I’ll draw a rectangle with blender…

[huitre39]

I would like to be able to create parallelepipeds with a texture (I don’t know if you can have more than one texture), bullet collision and reflection with render pipeline.
Is it mandatory to use a blender?

[rdb]

No, it’s not. If you use the GeomVertexData classes to create your own geometry, you’ll just have to be sure to add tangent and binormal columns.

@huitre39

You can do something like this to load non-RP models.

 # Use a special effect for rendering the scene, this is because the
 # roaming ralph model has no normals or valid materials
self.render_pipeline.set_effect(render, "scene-effect.yaml", {}, sort=250)

This snippet is taken from 02-Roaming-Ralph

[huitre39]

I’m going to use blender it seems simpler to me (i can create easily metallic or wet rock effect), I am able to have reflection.

I have a last question… how can I improve my performance ?

Performance Optimization — Panda3D Manual

i reduce mesh with flattenStrong but I didn’t understand how to “share the same state.”
is it possible to disable light effects on elements with render pipeline that are too far away?
I have 200 cubes but I’d like to have 1000 with 60fps (I have a gtx980), is this feasible ?

[serega-kkz]

I think the problem is what you apply .flattenStrong() is local to each object. I think you should first attach them to a shared node and call it on it.

@huitre39

I have a last question… how can I improve my performance ?

There was another thread on a similar topic recently, as I recall–I believe that it was this one linked here following:

Performance impact on thousands of Nodes

I planning of making a game something like mincraft in my free time. So there would be thousands of models at the same time. Even after instancing, there would still be thousands of nodes. Will that be an issue for the game? I’m not looking for crazy performance(24 fps is good enough). Sorry if it’s an obvious question. Thank you.

Perhaps you might find some useful information therein!

[rdb]

In addition to what @serega-kkz said, you also need to call clearModelNodes to be able to flatten multiple models together.

[huitre39]

thank you for your answers, I think you talked about this ?

I missed something ?
Is it compatible with the bullet physics engine ? Could I have “independant” collisions with my cubes? or will it be shared?

[huitre39]

I think I understood how it works, I was able to double my cubes (400) and I stagnate at 50fps

can we degrade the effects of render pipeline for distant objects?
I think it already does it automatically (maybe intern lod) but I would like to reinforce this effect.
or disable light and shadow effects for distant objects ?

[sazearte]

I don’t think it’s possible to have good performance with models.
it would be necessary to use panda primitives instead (with planes)

[rdb]

400 cubes is a lot to have as separate nodes, can you flatten them or generate them as part of the same Geom?
