How can I make a reflection layer transparent?

I want to make a window, I add a color material then lower difuse transperncy to have opacity BUT when I add an reflective layer it lose transperncy

also..

whats the main diference in reflection,refraction and emisive?

I added a material to some entity, poligon etc and I dont know how to change it or see what material it has, dont know how to check that in SU pro 8 and vray..

also..whats the big difference in SU materials and vray vismat materials?

and I dont want to print anything I just want to upload the renders to my page, but I want them better looking

I dont get it...now I render at 3000 px wide and the res is at 96....so how can I get it higher?

hmm.. i think you're unclear about what dpi means..

but using the 3000px example.. lets say you want to print it 10 inches wide

3000 pixels ÷ 10 inches = 300 pixels per inch (dpi)

now, change the print size to 20 inches wide

3000 pixels ÷ 20 inches = 150 pixels per inch

if you were able to adjust the dpi in the app, it would require you to choose a paper size..

so, say you choose 10inch wide paper then set it to 300dpi.. your image would be rendered at 3000px wide

set the 10" paper to 150 dpi and your image will be rendered at 1500px wide..

are you following me ?

.

I really are, but...so simple I dont get it, when I render something in vray at 1024x768

and save them to image formats THEY ARE ALL in 72 dpi, then suddendly it gets to 96....

so to get better pictures I have to use the irradiance map min rates and max rates|"?>

I dont get it...now I render at 3000 px wide and the res is at 96....so how can I get it higher?

I want to render above 150 or 300 plz tell me how, thx

hi..all my renders are 72 of resolution, they look really pixelated, how can I have the jpg files at 300 ?

Edit the image in Gimp or Photoshop.
Save it as a PNG format if it's not already.
Add a alpha channel.
Select the white pixels using a 'magic-wand' and delete them.
The background should now look transparent.
Tidy up erasing stray pixels etc so it's cleanly transparent.
Save the PNG.
Import it into a SKP as an Image.
You should now be able to see through them.
The shadows cast will be rectangles still.
to fix it...
Make a group [or probably better, a component] containing the Image.
Edit that.
Explode the Image into a face with the equivalent material applied.
Draw some edges around the outline - doesn't need to be too exact for a 'shadow'...
Erase the unwanted parts so the object now casts a shadow approximating to its 'real' outline...
You don't want to see the edges around the thing so Select all and deselect the faces by holding shift+ctrl as you click on them.
When Entity Info shows that just edges are selected you can tick the 'hidden' box so they are not seen and all you see is the face[s] with the image applied...
I'm sure there are some threads about this - learn to use the SCF Search tool [>3/ charcaters], your browser's built-in page search [Ctrl+F] and Google's site search site:sketchucation.com xxxx - substituting the 'xxxx' for one or more things that you are looking for...

ok but what if I dont have the picture because I download it from google warhouse?

just tell me plz how to take that out, thx

Hi memo333,

As to closing the gap, have you drawn a line from one corner to another? If that does not work, you probably have a gap somewhere, that needs to be closed. These gaps can be tiny, so what I do to find them is to draw many lines, creating parts of the face I originally wanted to create. That encloses the area of the gap so that you can find it. Close it and delete the lines, your done. Here some screenshots to explain:

So I have the shape and want to create a face.

I want to close it up, but only half of it does.
[attachment=3:7qcvuxh2]<!-- ia3 -->Sketchhelp2.PNG<!-- ia3 -->[/attachment:7qcvuxh2]
I draw more lines, creating more faces, enclosing the gap causing the problem.
[attachment=2:7qcvuxh2]<!-- ia2 -->Sketchhelp3.PNG<!-- ia2 -->[/attachment:7qcvuxh2]
There it is. Close it and you're good to go.

What exact transparency do you mean?
And try just googling Vray tutorials, there are many good ones out there. I believe Vray actually has a handbook in .pdf, which explains how to use it pretty well.

when I render the texture white color appears in the render, I just want to take it off, let me show
