Very new to Kray (1st day), and I'm trying to apply some of the things I've learned from Jure's tutorial ( http://www.kraytracing.com/forum/viewtopic.php?t=411 ), but having a bit of a problem. 1st problem seems to be the size of my scene/objects compared to the one for the tutorial. I've imported to see the size difference, and my objects, etc. just dwarf his. I'm in the USA, and my objects are just in ratio to the CAD drawings imported from clients, so it's not like I super sizing them. Now I know I can adjusted that in the light settings, but just wondering how some of you have set up a work flow to handle that.

You could size down everything in modeler, or if that's not possible, you could parent everything in layout to a null and then resize that null as needed.

It's generally a good idea to have at least roughly, realistic and proper sizes to everything.

I'll try the null suggestion

The only problem with that, is like I said, I'm basing th object sizes off of the plans given. So if I start modeling a project after resizing it, then get updated plans, I have to resize that newly imported drawings at the same resize of the original. I guess that would be better, at least they would be LW real world.

I'm not sure I understood why you can't work on real sizes from the start, but if you use the null method, the models will still actually have the original size so I don't see what the problem will be if you get changes to the plans. and whatnot.

Is this a default units issue? Jure's scene will be metric while yours will be US. Jure will be working in either mm or cm. Once you work out the conversion factor it should be easy to check the difference and scale the relevant objects accordingly.

Learn to love the metric system!

NOOOOOoooooooo... Actually I use LW's standard measuring system, I have no clue what they are in real world measurements, but working with LW long enough I've relatively got the hang on the ratio's with in the system. It's like I said, I'm just importing the dxf drawings from LWCAD, and using those size. I wish LWCAD would convert the CAD size to be correct in LW once importing.

The unit system in LW can be SI, metric or English

You may find that LW is just getting the decimal point in the wrong place. I frequently import things and find they are several kilometres long instead of several metres (ie LW has interpreted millimetres as metres).

There's a remarkable plugin called Dimension+ which is so useful it should be standard kit for everyone. You can use it to specify the absolute size of whatever you've got selected in Modeler. Download it from http://www.giannisoldati.com - it says it's for 7.5c & 8, but it works fine in 9.3.1

NB if you want to undo the effect of the plugin, you have to hit Undo three times. Not a real disadvantage considering how useful it is.

Lightwave uses metric, internally. If you make a model four feet wide, for example, the actual data in the file is the equivalent in meters. Choosing a system basically just converts the display and input, it doesn't change the data itself.
