Slight real time transparency anomaly in.

Edit: No need to try this anymore. I have ascertained enough to send a bug report. Thanks!

 

load this PRJ, select the camera view (number pad 1), and select model you see there.

 

Switch between Director mode and Skeletal Mode. Can you see the shade thru the window in both modes or just one?

What graphics card do you have?

Can see shade in directors mode, but not in skeletal.

 

However - if you change the transparency to 100% - you can see the shade in both modes.

 

I also noticed that there was a problem with partially transparent objects casting shadows or reflections (can't remember which) when I was doing my Lothario & Ida dance animation. Image (reflection I think) would pop when it went from partial to 100%. I eventually just moved the camera so it wouldn't show the pop.

Here's example of popping (I changed a bunch of properties in your models - but in these 2 images the only thing different is that the model goes from 75% transparent to 76%. It's the RIM z-buffered shadows that pop. Other lights are turned off. Ground is 99% reflective in both cases (changed to gray, 100% diffuse falloff).

I dimly recall that the shadowing difference is a limitation of z-buffered lights. I might be wrong on that but I think Martin said something like that once.

 

The work-around was to change the light to ray traced.
