martin, i've located the x-crossed palm trees, i've walked twelve paces in the direction of the setting sun, i've dug down exactly five feet, three inches, i've found the brass spangled oak chest, and i'm seated in front of the treasure with only one thing missing…..the key! how, beside trial and error and two thousand microadjustments to u and v offsets and scales do you manage to get the "letter opacity maps" to fit EXACTLY into the holes? i spent the entire morning sliding a wee bit to the left, and then to the right, and then a tad wider, then down, then narrower, then, then, then…..thinking all the while, "boy, i bet martin has some little trick that does this in about two seconds flat and wouldn't he just be laughing himself silly to watch this oafish attempt to thread the needle. well? is there a simpler way to do this other than trial(s) and error(s)? with baited breath, michael

Mick, firstly, it's best to use my CI$ ID# – I almost missed this message completely and you would have suffered alone. >> how, beside trial and error and two thousand microadjustments to u and v offsets and scales do you manage to get the "letter opacity maps" to fit EXACTLY into the holes? << A trick I've used is to set up the opacity flic as a background and turn on the background in the top view – or whatever view you do surface/mapping. Now move the _geometry_ into place over the top of the background using the viewport zoom and pan icons. You can now do a surface/mapping/region fit around the outside of the background bitmap. Make sure in the info menu/system options that background preserve ratio is YES. Also, note that you should probably allow a little overlap in your opacity map (see the one I included) but not too much because it will encroach on the neighbouring letters. Good luck and let me know if it helps.

martin, thanks for all the good information. i've still got little visible seams but i think i'll bite the bullet and repaint the opacity maps. unfortunately, my letters "10 YEARS" are in a semi-circle which makes the mapping adjustments just a bit more tricky to see but i will use your technique to achieve better results. sorry about the CIS id thing. I have your name, company and # in my directory and thought it would automatically add the # after i typed your name…..obviously, i was incorrect. i'm still encouraged i can pull off this effect…..many slips between the cup and lip! thanks, michael

Michael, >> i'm still encouraged i can pull off this effect.. << I hope it all works out. Sometimes some repaint is necessary – that's why I use Animator Pro – you can shell out quickly and make adjustments or have it running on a machine next too the 3ds station.

martin, amazingly enough, it's all done and looks rather spiffy although i used spurting sparks instead of flame (it's cutting through a gold ingot and i couldn't get flame.axp to remember its secodary data motion) thanks for the support, tips, and encouragement. michael

>>making map fit… Michael, I'm afraid I missed the first part of this discussion, so I may be way out of line or way behind here. When I have geometry I need to make a map to fit, I generally create the foundation of the map by rendering a ortho view of the geometry from within 3DS. (I think with white self-illuminating material applied to get just black & white) This bitmap is then loaded into a paint program to invert, edit, paint, etc. I think this is pretty standard technique so I apologize if you're already tried it. I once needed to opacity map letters precisely around the perimiter border of a disc-shaped object. Rather than 1st trying to make a map and make it fit, I found it easier to create temporary text objects in the shaper, bend and place them to fit, then render an opacity map. JKJ

JKJ, >> Rather than 1st trying to make a map and make it fit, I found it easier to create temporary text objects in the shaper, bend and place them to fit, then render an opacity map. << this is basically what I do. Then for an animated opacity map just paint out a bit at at time and insert a new frame in animator pro. It's repetitive but works. Or you can have 3ds use an animated stand-in paint brush which will guide you as to where the real brush should be in time.
