ok, Playing around with my house, I wanted to see if it was piossible to decorate inside....but when I put the camera inside, I could not see out through the booleaned windows.... is this normal? and to I have to make multisectional walls to fix it? Thanks Jen

Hm. Interesting. The camera should work from inside a booleaned object--I just tried it on a simple cube-sphere boolean. It might just be that what you have there is too complex a model or file.

Jen, maybe you have something blocking the camera view?

I'd guess you didn't get the camera far enough inside the house.

Is the inside of the house booleaned out or just the windows?

Aldaron, That's what I was thinking. JC, If you made the house out of solid cubes there is no way a boolean will work from the inside ... unless... if that's what you did, duplicate the house, make the xyz's of the dup a little smaller and group the outside(+) bool to the inside(-) bool. Then you'll have to seperate out the window and boolean a hole(-) the size of the window to the house group(+). then insert the window into the hole and optionally group both(+). - TJ

Hi Jen, Seems I had the same problem working on the bates house.....did you try putting a light inside? Try viewing the camera from top, and side views.....sometimes things look different than they really are. Also might want to try viewing the house in solo mode, perhaps some of the trees are making things inside too dark. Btw, didn't get a chance to tell you before, you did an awesome job on that house and the landscaping around it :) Let me know if you figure out the problem.....still not sure what I did to fix mine lol.

yea, in the middle of working on it someplace, I took out the interior - booleans... so it's a cube with windows...lol When I tried working with the house, there were sooo many objects in that cluster, I decided to use a few less...LOL One thing I do know.... I'm not about to regroup 13 windows again...LOL I'll just have to rebuild the house hahahahah actually, I want to make it like a model house...with an inside and an outside....would love to start making furniture and stuff for it....grins the house model itself, while there's lines everywhere, isn't that big, but the whole scene file got to be pretty big...lol thanks for the help everyone, and thanks Teri, it's kinda like a picture of my dream house...lol Your house came out around the same time, and it looks fabulous..grins Jen

Ahhhh, yes, of course Jen. Bryce boolean are not real booleans and doesn't work like booleans in other modelers. As for grouping the 13 windows, you can select them all once and put them into the same select family giving them their own color. That way, whenever you need to select all the windows at once later to group them, you only need select the family color to select them all in one click.

What Quest means by that statement is that Bryce uses the boolean technique for filtering layers. So when you are using a grouped pos-neg combination, what's really happening is the negative is "hiding" from the raytracer, with a cool option to paint the texture onto the positive side. I first ran into this when I was hollowing a sphere for use in one of the contests. To illustrate, make a sphere, duplicate it, shrink the duplicate, set the first to positive and the second to neg and then group them of course. Simple enough! I cut through the spheres (now ungrouped again) with a plethora of randomized negative skinny cylinders, to demonstrate what's happening here... The mat for the first is stock red plastic. The mat for the second, inner sphere is ANY volumetric, with density at 100, no fuzz, no softness. Volumetric materials will not render on the inside of Negative Booleans, apparently. Make any sense? It totally does until you try to set the MAIN, POSITIVE sphere to the same volumetric, which renders what you see on the right. Same scene, nothing different except stated materials. So, aside from personality quirks (me), there are problems with our favorite raytracer (Bryce)... But, in my experience, this would have nothing to do with the interior of a house/building/structure. You may just need to re-examine your hierarchies, I've made very complex structures (Black Tower, i.e.) and shot the camera around inside of them just fine... What I mean is, that you CAN make your interior happen, Bryce WILL let you do that. Just takes some planning, and serious attention to grouping and hierarchies. The above image was merely to illustrate what Quest meant about UnTrue Booleans.

And here's the scene from outside the Grouped, Booleaned sphere/cylinders... (in case it didn't make ANY sense, which is often the case with people who have ridiculous screen names...)

JC_01 posted Mon, 06 October 2003 at 8:55 PM

LOL thanks...I read that was was like huh? so thought I better read again when I'm not so tired...LOLI'm gonna try to get something rendered for it, but it seems to take forever, even for an inside view....lol

(sorry about the lack of AA on that last one, I'm at work, no time...) Those renders are Bryce 4, but Bryce 5 has the same issue. Any workarounds would be wonderful?!?!?!
