Hi all.
I need help to finish my stages. There are in this moment 3 good ( in my opinion  ) stages now. The problem is with the objects. I'm using BTB at the moment but it is not worth to continue... The plugin just doesn't work with RBR and objects. Ok, it works with few but not when you have to put many objects to get the stage visually good and great driving experiement. If I put over 4000 objects the game performs so poorly. What should I do??? Stop creating new tracks??? I want to share my tracks but first I have to finish them.
OK, I know about Wally, and if I get his support I'm ready to rebuild these stages in max, but first I wan't to know if there is any way to handle so many objects through BTB.
But still... BTB RULES |

first off, just because the plugin can't handle 4000 objects doesn't mean working with BTB is not worthing, you can still use BTB in conjuction with max and Wally's support.
the plugin as it is now it just an experiment and it has it's limits mainly because it does not enforce a material(effect) or mesh type.
RBR's gfx engine has only one material type for terrain(with 4 variants based on shadow and specular combinations) and also only one material type for the track objects and these materials are based on quite simple effects coded for shader version 1.4 and below.
the low shader versions means speed and the low material count means many objects can be joined together in big chunks for even a faster rendering. these two aspects can still be acheived with the plugin too: simplify the effects, reduce the number of different material types and join together all the objects sharing the same material.
there is also the issue of the movable objects which require a special kind of shader (an instanced version of the one used for fixed objects) and from what i know Piddy is woking on creating such effect versions for the materials supported by BTB but i can't tell you when they will be available or how much the performance will be improved(in theory and from my tests so far, it will be considerably faster).
i'm also working on a new version of the plugin which should have better performance at the expense of freedom but i can't tell you to wait for it, you should do what you consider best but please keep in mind BTB and the plugin are totally different things and even if you use max BTB, from what i know, is still one of the best chices for fast and easy track creation tools and i'm sure you will find a way to export your work from BTB to max without much trouble. |

Thanks Black f. for quick reply.
I'm just a little frustrated. I appreciate your work for the plugin and Piddy for great work with BTB. I'll try first what you suggested about the materials.
"reduce the number of different material types and join together all the objects sharing the same material"
Can you give more info about how to join the objects sharing the same material ? Can I do it in BTB or how? Or maybe I just don't understand what do you mean with that.
Sorry for my English....

@ black f.
Just one quick question as I just read abot you making new version of the plugin. Is there a chance that you and Wally stick your heads together and combine the knowledge into one great plugin?
Or will Piddy add suport also for native rbr export format?
It's just a question. nothing personal ok. |

Wally knows the RBR track formats much better than me so doubt he'll need my help, beside i'm not interested in the old formats anyway.

i'm not the one who should answer to this but if i were to guess i'd say is unlikely.
@MetalX: you should do some tests and check what BTB actually exports.

Care to post your track? it might help identify what is slowing things down. In BTB 0.5.0.1 I can have 10,000 trees and still have great frame rate.
XPacks objects will give poor results if:
- Objects are very complex
- Textures are too large.
- Textures are not being reused on multiple objects.
Of course, a complex model can be nice here and there for close to the road situations, but using many of them will start to kill frame rates.
That said, I am working on BTB 0.6 which is to include a few changes to the RBR plug-in which should speed some situations up.
As black f mentions below, he is also working on a substantial change to the plugin, so I'm not about to spend too much time tweeking the existing one.
