Tutorial about making bugless colissions in SketchUp. This video is English, and I'm Dutch: I got quite an accent, but I think it's understandable. Be sure to watch it in "High Quality"!

One thing that I forgot to say in the video, is that it does not matter how the faces are turned (blue or beige, invisible or visible ingame), because the colission isn't visible at all ingame and a colission works from both sides of the face.

I use this method every time, also for my Colosseum, which was quite a difficult model. No colbugs ingame though! That colission was 4500 poly's...

I use it all the time, I can assure you that this works.

If you use other tools than the pen, it could be possible that bugs will appear though, so only use the pen.

For example, this is a SketchUp model by me and has no colission bugs ingame, such as invisible walls etc.:

This is my colission:

And yes, this took a few hours to make, but the result you get (a bugless colission) is really worth it. Even if I had made this model with 3dsmax, I had to make a colission, because the dff-model is 20.000 poly's biggrin.gif The colission in this case is around 4.500 poly's.

Nice one puma
though it would have been a pain in the ass if you have modeled all that
you just modeled one part and then copy and paste NICELY DONE XD!!!!

Congrats Looks great ingame now sell it people will surely buy it

Puma can you make a Vehicle Modifying tutorial? like exporting it to the game and stuff?

As I have mentioned 'a few times' already: only use the pen.

For sketchup users: Can the col bugs I read about be from not using proper modeling techniques? Not using quads, keeping triangles rare in the mesh, weird cuts/draws at unnatural angles, etc.

I recently played with a 3ds exported from sketchup and I was very like "whoa, how did this even get made? These faces are insanely incorrect." Will proper mesh structures help? Because I think it might be the issue (it seems like maybe the ease of construction comes with a cost of poor poly flow). Does this make sense? Can tighter standards on how you build your actual mesh aid in this? I must also say, I can usually model what takes hours in sketchup in minutes in max - I just have enough tools at my disposal. Is there a reason why people prefer sketchup? If it is for ease - the cost in time makes the ease unfriendly, and the cost to poly flow and fixing things seems to make it more trouble than it actually solves.

Make sense? Or is it something else? I'm not bashing sketchup (I see it done on here, and I don't want to come across like that), I just have this assumption these are the reasons sketchup is being used, and I feel like maybe they are counter-helpful in the end?

@tutorial: Your english is fine, continue these works, this modding community needs this kind of life added. music is or is not needed, maybe it can be easier to follow without AWESOME song like teenage wasteland distracting smile.gif

That's weird, it works for me. Are you sure you set all default colours to white and applied the material to your model after editting?

The song is called "Baba O'Riley", but it is often called by many people as "Teenage Wasteland".

Further, it doesn't make any sense how you model: if you only use the pen, and then only use the pen, you will not get any colbugs ingame. You can use scale, rotate and move tools though, because they don't change the model itself, but only the shape etc. so the structure stays the same.

One thing though, Puma, the way the collisions are facing are used for the camera culls. The camera will pass trough a inverted collision face but not the other way around. turn.gif Try it

... Didn't work as I only saw white in top of my textures. Also, I don't have collision bugs as of right now with my models, so I am okay.

Awesome was looking for this as the way I knew was in max and if it had too many polys the col would be all crumpled. Not anymore!

I knew there's a way to export right collision data without bugs using the already made .x plugin and then removing unneeded lines using a text editor like notebook or notebook+.

But that's only the case if you are working with a Vice City collision...... then again, you can convert collision versions using SteveM's Coll Editor 2, so it isn't a big deal. If I remember right, there's even a topic about that here. smile.gif

Gee, I would like to know how to do that. I have a Sketch but it gives me COL bugs due to the fact that I used tools other than the pen.
