Hi everybody I am new here. I just dusted off my copy of truespace4.3. I have been wanting to make a fantasy I have had into a movie.I know there is alot to it. But, I figured it would be fun and it would give me practical experience in 3d arts, something i have always wanted to know well.

So , starting off I wanted to build an animated motorcycle. I was hoping it would be relatively easy. like pulling strings on a puppet.I first thought I could do alot with the physics simulatiion.How wrong I was!I realized this when I tryed to spin the rear wheel on its axel.And ts just spit it right thru the axel.So I have started keyframing it (oh boy is this going to be tedious)

My question is this , is there a way to key frame both wheels at the same time .like if i rotate the rear wheel 10 degrees the front will automaticly rotate 10? also is there a way when I create a path for the bike that the wheels track and rotate and suspension automatically react according to the ground? Sorry to be long winded.

Thank you very much,

Good luck with your project, but I think you should take time to experiment

with the software. check out this site for making animated vehicles.

Im not sure what versions of trueSpace VCtek is for.

yea, I saw an article on this forum early that pointed somebody to caladonia.It looks like a great plugin but I can not afford 20bucks for hobbies right now.Also,for me to progress in any form of study I need something as a goal, a bright light on the horizon.So when I come to problems I solve them and it makes it fun for me. so if i need to solve a problem I use simple primitives as an experiment an then apply that to the model. btw,I finaly have a computer that runs 4.3 very well.I hope to max out my abilities in 4.3 before moving to the latest upgrade.

On a 2nd note, when I eventually upgrade to 7 and I want want to upgrade further can I export my models/scenes to 3ds max?

Thank you cammer

If you can't affort 20$ for a plugin, how can you afford 3ds max??? Just curious.

Exporting scenes would be quite difficult, but object export via luuv plugin, which is free, should work fine (wavefront obj format). There's a good converter called deep exploration, which can convert scenes as well (many formats). But there are only limited features that are converted properly, especially animation is very limited.

you can save\export out of TS to 3D Studio's format - .3ds but this would be each object separately. Although I suppose you might be able to glue the whole scene together as one big object and export it.

Animations and scenes are typically more software specific.. although I believe programs like motion builder are trying to be\currently are a standard for cross compatibility.

As to your earlier questions, you could use a plugin like Trueconstraints to have one wheel act the same as the other..there is also a plugin called Wheelwright that will figure out rotation based on the distance you move an object. These combined with "look ahead" might give you some decent results.

both plugins available at CK Game Factory.

The suspension and stuff could also, I think, be configured with Trueconstraints but it would take some set-up.

I am in a financial slump right now but I hope to get out of it eventually.Also I am a dreamer and like to think long term. And thank you for the information on 3ds max ,it is very helpful.I was just trying to determine if was best to stick with 4.3 till I can afford max or use 7 as stepping stone.There are a lot of varibles ,but it is good to know my models would be able to transfer.

Thanks again

Sorry I haven't followed up,but I am having a hard time understanding Tru Constraints.The online tutorial is too brief.I will figure it out eventually i am sure, is a privately held community resource website dedicated to Active Worlds.
