Bryce will take a greyscale bump (or displacement) map and convert it to an elevated terrain. I believe this can be exported as a .obj.
Yup certainly can. This method is used to create a city block - or to create a greeble panel - I’ve done that myself.
I’ve never used it to create a terrain to use as a terrain, i.e. from an aerial view drawing of an island or continent, with shades of grey indicating heights.
Create a terrain, click on the E to enter the terrain editor, click on Pictures, then on Load (see pic 1) then browse to find the terrain map you want to use. Mine are in Progfiles/Daz3D/BrycePro/Terrain Maps – your drawing will obviously be somewhere else. I’ve chosen ‘City1 mask.TIF’. Click on Copy (step3) then Paste (step 4) (see pic 2) then click on Elevation (step 5). Click on ‘Raise/Lower’ (steps 6 & 7 in Pic 3) Then, (see step 8 in pic 4) click on ‘solid’ before leaving the terrain editor (step 9) and there you have a city block. You can then either texture it with a city map from the presets or export it and add UV maps in another app.
I’d love to see what you end up with from this, DarthD.
