Hi all! First, I want to say "Hello" to this community (first post here), then a quick question: how do I create a dome to texture the INSIDE with an HDRI image? Thanks!!!

Hi and welcome, just take a sphere. Bryce's spheres are hollow. J.

Blow the sphere up real big so the scene and the camera are inside. You also want to either put lights inside or turn off cast receive and self shadows in the materials so light can get inside.

With a HDRI mapped to the sphere he don't need lights inside, electroglyph...

I don't know how to load HDR files into Bryce 5. I think lightwave will use them. This is a jpg from the site Agentsmith posted a few threads back. http://hdri.3dweave.com/library/ These are the default 100 diffusion 19.6 ambience settings that pop up whenever you apply an image texture. looks pretty dark to me. Maybe you could explain a little better how you actually apply a hdr to a sphere in Bryce? It seame to me you have several choices. Kick the ambience up to 100 which makes the hdr image bright but still leaves anything you put inside in the dark, add lights inside, make the sphere permiable to sunlight by turning shadows off, do a true ambience render.

I've yet to do one of these HDRI thangs that I'd be willing to show anyone, so I look forward to hearing any tips that come along. 8)

Here is an image with the plane 1 removed. I've inserted a bryce cube with default texture into the center. there is no flat ground just the projection of the hdr sourced jpg on the sphere. This first one is diffusion 100 ambience 19 with shadows off in the materials and bryce sunlight shining through the sphere. The sun controls appear flipped. I had to set the sun position in the upper north quadreant of the control in order to light the south side of the cube. you can also see shadows around the edges where the dome appears dull. Turning off link sunlight to view does not cure this.

Heres an image with no lights and sunlight off using true ambience. diffusion and ambience are set at 0 and 100. the grainy texture on the cube was a product of the render, I did not change it. This took about 2 minutes to render.

Here is the third and final render. Sunlight off diffusion 100 ambience 19 and one radial light at default 25 linear falloff set inside the sphere. This took about 20 seconds to render.

Thanks to everyone - I'll try as soon as possible!

electroglyph ...could you please refresh my memory on how to control the sun again.

Click and drag on the sun circle on Sky&Fog menu. Or go to Sky Lab and change the values in Azimuth and Angle (Sun Controls on Sun & Moon tab).

This site I've linked to explains much better than I can what hdri is and the physics involved in the images. It even explains why the image is LDRI (shifted blue). The great thing about the dancing bear...ops, The great thing about hdri or in this case ldri is that it ads a 360 realistic reflection to metal or glass objects in your scene. Here is the same image with a chalace inserted. The chalice is about 180k and the hdr image is about 340k. Imagine building an entire town square with 20 buildings, a few poser characters 200+ plants an outdoor cafe just to produce this same shot. It would take gbytes of memory. In bryce you would also be waiting while the rays are calculated off each window, down the alleys and back to the camera. With the hdr you're not really calculating the path of lightrays as they glance off buildings, You're just calculating the bounce off the sphere and back.
