rpc and nxt ..unusal shadow line appearing

[mike makki]

I have re-rendered this and added extra light source..however there are some unknown shadows appearing at the end of her feet....its an rpc ...

I have lowered  rpc below the surface still no joy...any thoughts roy... al..anybody...?

Check the units first-- try _DDUNITS and make sure the insertion units are correct for your drawing scale.

[mike makki]

its doing it in all rpc....very strange....i think its a render issue more than rpc issue

[Alejandro Testa]

Are your objects near to the  origin ? WCS 0,0,0

[mike makki]

it shouldnt matter....i have had this problem before.... i think  the rpc arrow insertion you get when you

insert them stays and create the shape on the surface of floor etc....have you tried it in interior shot?

[Roy Hirshkowitz]

Check the units and insertion point.  It can matter.  It can create precision problems in the render engine which can absolutely cause problems such as yours.  It could, of course, be something else....

I have this problem before, and   usually this happen  as a precision problem or when I use some particular  RPC. Also when I  have this issue I clean all the temp files, and reboot the machine starting again. Hope this help.

i have checked the units...its millimeter...my usual scale....checked the wc`s 0,0,0  its far from the rpc.....

so...there you have it....

If you have time, try moving the model closer to the origin and see if the problem goes away.

[mike makki]

still the same result...:(

[Roy Hirshkowitz]

If you have a chance, upload the drawing and I'll take a look.  Moving the thing close to the origin almost always fixes this.

[mike makki]

hello roy..it didn't work

[Roy Hirshkowitz]

What didn't work?  Did you try to upload the drawing?
