Reflection maps
by Matthew Jones · in Artist Corner · 07/19/2004 (4:18 pm) · 8 replies
I am not new to making models for torque and recently in THIS a few bugs have been tweeked out so the MAX exporter now work with MAX6. Not all the bugs are worked out though. The main one for me now is the fact that you still need to use a seperate reflection map and diffuse map.
I was attempting to make a reflection map similiar to what I would use in and alpha channel on a regular 32bit png. Mainly the texture would shade in areas hopefully creating more reflection in certian areas of my model.
I noticed after getting the model in to game that it flickered on and off from no reflection(emap) to full reflection.
Am I wrong in thinking that a shaded alpha channel in my reflection map should produce the effect I am looking for or is there some bugs that prevent this from taking effect. Or does this only work if you rely on the alpha channel in your diffuse map to set the tone for reflection.
Any help is appriciated.

I would send you an example scene but I am not sure what you are running MAX5 or 6.

You have make a seperate image aside from the one you are using for a diffuse map. It has to be a 32bit png image.I would send you an example scene but I am not sure what you are running MAX5 or 6.

Matt are you having issues in both R5 and R6 or just R6?

Some people say e-maps only work on moving objects but, I have had other people tell me that you can also get them working on static objects too.

MAX 5 with MAX4 multires and the bravetree exporter apperanlty kickout good. So I answered my question.
I guess there is a fix for the max 6 but the guy "Sammy NG" hasn't posted it yet. Here

None at all Matt, sorry. If its an issue with the exporter that has been compiled I don't think that you can work around it :(

Then Check the reflection box, and it will take the alpha channel as the opacity for the reflection and it will not flicker as you mention above (happened to me also)
You can also work the transparency in photoshop to add more reflection to some places than other, it worked because I tried all this.
I hope it works for you!!
Really I don't know why it worked but it worked perfectly for me, you should try and post what happened to you.

There's a way to work around it, unlock the ambient texture and apply the same texture from the diffuse channel to the ambient channel, this will unlock the advanced capabilities..
