hello i need help on how to make perfectly collisions for example if i make a box that is opened it will let me put stuff in it but when i try to do this the box is like closed. how can i please make the collisions perfect :(

I have updated the Collision Hull docs to include this example image:



Remember that your model needs to have the $concave option checked in WWMT as well.

so i need to seperate the parts of the collision hull?

[wallworm]

Yes, they must be separate. However, they do not necessarily have to be separate objects. They can be in the same mesh as long as each piece is its own separate Element.

Watch this video.

video is too long and all i need to know is hwo to make the collision not all of this stuff :/

Well, in the time since asking the question and until now, you could have watched that video several times. It goes over all the tools in WW to create hulls that match objects and discusses all the principles. I suggest watching it or reading the hull docs on WW. Also, most of the buttons in WW have tooltips when you hover over them to explain them.

To add multiple objects as hulls, select all the pieces and hit Add CM Sel. Make sure $concave is checked.

sorry for that rude message and thanks for simply tell me how to do the collision XD thanks alot /)

Don't sweat it. Just remember that I don't get paid to provide support and expect all WW users to share patience and respect if they wish to receive my input, help and experience.

im sorry to say this but i know i gonna look like a noob but i still cant do it i tried everything. could you please make a simple video on how to make perfect collisions on a open top box? if you have time. please

[wallworm]

I'm not sure how much clearer it can be than the image I posted at the top of this page.

Make the open-top box model and assign it to WWMT as the model.

Make the hull. You can do this with five boxes: 1 on the bottom, and four around the sides.

Select those hull pieces and in the WWMT UI select Add CM Sel in the collision hull menu.

It's straightforward.

oh alright thanks i will try it and sorry for  bieng a noob

[omegadavid99]

forget it...i did what you told me ands still wont work just forget it  thanks anyway for trying to help me

[wallworm]

Don't give up so easily :)

Well there is one setting I mentioned earlier but not in last post:

Make sure $concave is checked.

Also... I'm attaching a sample scene in 3ds Max 2014 format that has a box, a hull and a WWMT already set up.

[DELETED AND ADDED TO POST BELOW]

[omegadavid99]

erm.. im using 3dsmax 2013

[wallworm]

OK... here is a newer sample scene zipped in what should be compatible back to Max 2011. I also updated it to include three different box models with different ways of making the concave hulls.
