View Full Version : Rendering Videos?

Hi,

I'm new to Lightwave 3D and I was wondering where I could find some good rendering videos (commercial or free tutorials). I'd like to learn the nuts and bolts, and not just memorize some steps.

I would like to learn how to re-create these surfaces... http://www.newtek.com/lightwave/v92/

I'd also like to understand DOF and Motion Blur in Lightwave too. The samples in that link are just super! :D

It's too bad Digital Tutors does not offer LW videos...

BTW, I'm going to buy a new PC setup for games and 3D apps like LW3D. Can anyone recommend a good videocard? Also, does the CPU have a lot to do with 3D app performance (like calculating dynamics, rendering, etc). And what about 32-bit vs 64-bit, is 64-bit in LW much better?

Thanks,
Leo

The Handbook that comes with LW would be my first look. Not everything is explained in depth there but its a good start.
Then there is this huge list of Tutorials: http://members.shaw.ca/lightwavetutorials/Main_Menu.htm

And finaly Kurv Studios sell videotraining material:

I would recommend a nvidia 8800 GT. Its the best bang for the buck right now.
The CPU has the biggest influence on calculating anything. The GFX card does not help there.
LW 64 can hanlde much higher scene compelxity because it can use much more RAM. I would go with 64 bit windows. You can still install LW 32 to use those plugins that are not available for the 64 Bit Version.

I would surely like to see Digital Tutors offering some tutorials aswell, they seem outstanding
in terms of how the voice instructions go along from the tutor and very clear and easy to follow with a sweet videointerface divided into proper parts and to long videos covering
each topic.

Desktop images has a lot also, older stuff from lightwave 7 covering particle effects,hypervoxels and lately a visual fx series with jarrod davis and a lightwave 9 defined
box, covering advanced camera tools and some node stuff, donīt know how good it is thou.

The materials that you linked to are in the Nodes section. Add the relevant node (conductor for example) & link from the output to the material input of the surface.

As for 32/64bit. If you have 3gb RAM or less stick to 32bit. If you have more then consider 64bit. Personally, I'm running XP x64 with 4gb RAM & for Lightwave I haven't noticed any speed increases. XP64 also isn't very well supported outside of 3d so you might have trouble running games & some plugins don't work either. Unless you have a dedicated workstation I'd stick to 32bit.

Thanks for all the replies! :)

As far as just plugging in the nodes, I tried that, and my surface tends to go black (atleast with dielectric). I know there must be some tweaks we have to do to get them like those on the link.

Too bad the manual doesn't show you the node tree for each one of those...

heresīs a start video for dielectric glass http://bytehawk.net/content/view/25/47/

thereīs no scene provideded for this thou so you might run in to some problems
getting the same results, especially getting that black areas in glass, probably ray recursion
settings that should be set higher.
in the dielectric material absorption and color settings are very important and changes the
look dramaticly.

I suggest check newtek.com forums theres a lot covering nodes over there.

If you're running 9.2, you probably need to activate double-siding for your surface, and make sure that you have raytrace refraction (or one of the raytrace functions) active so that the shaders can measure the thickness of your material...

I was gonna also suggest looking at Essential LightWave 9 (http://www.amazon.com/Essential-LightWave-v9-Fastest-Easiest/dp/1598220241) - Its got 14+ hours of video tutes on the DVD, as well as 964+ pages of LightWave 9 essentials. :)
