I don't know how many of you use blender... But I'm currently trying to make characters in Blender, and I saw two different methods I could use thusfar: One is making a high-poly mesh and sculpting it using different tools. The other option is to take a base drawing or image and then create planes and extrude vertices to make face loops and connect different faces and create models that way.

Which do you all think is better?

Well, just remember that models used for games shouldn't have much more than 4000 poly's. You can add more detail with shaders if you need more detail.

Okay, thanks! I think that gives me option two.

I'm using [href=this]http://cgcookie.com/blender/2009/01/09/modeling-a-human-head-series-part-1/[/href] approach to modelling.

I'll post some art when I have it done.

however a sculpted model could be retopoed into a lowpoly model: its all about preference here


The result of origin.. Oh and ponies

Yep, either that, or use a program like Sculptris, Import the object into blender, Make a clone of the sculpted model, Decrease it's polygon count (with decimate or poly reduce), position the lowpoly at the same place as the highpoly, UV unwrap the Lowpoly, add a blank-black image, then go to the Render options, go to "Render", go to the "Bake" tab, click "Normals" and on a box, go to Tangent, then Bake Active to selected or something like that, then click bake, should be a good alternative

Well, there's a reason I'm not doing that... I've heard numerous times that blender isn't good with retopoing meshes from a high poly count to a low poly count.

it'll retain the overall shape pretty well, but it messes with the loop flow. It's workable but you need to invest some manual labor to clean up the mesh afterwards.

you're better off starting with a low poly base, then duplicate and use multi-res or subdivision on the copy to work up to higher detail levels and bake them back down to the base.

or if you're set on doing the high poly first, use the snap tool set to volume (to snap the new vertices to the surface of the high poly) to manually build a new low poly mesh around it, and bake them down.

I'm thinking about doing something like that... my head model is nice in detail and all, however for some reason a good chunk of faces in the forehead and around the face are transparent when I set up blender to show textures, and when I set seams up to that area it doesn't draw textures at all.

transparents sound like you are seeing the back-faces. select those faces and flip the normals. you can try to simply recalculate the normals to outside but depending on your model that will sometimes just flip some bad ones to good and good ones to bad

I managed to get it working, thanks!

BTW, I'm wondering, (and maybe you can help me with this...), does The directx exporter for blender already flip Z and Y for you or do you have to rotate your model 90 degrees?

Thanks! That saves me an extra step in blender.
