Photoshop, illustrator and Sketchup Viewer are not rendering programs, so if you're not doing the rendering i'm wondering if your receiver can actually do so... but that's for you to find out.
If you don't have access to 3DS Max through a suite or collection then you'll need to purchase it.
A possible free alternative could be Blender, but you'll have to learn how that works just like Max.
(and it doesn't directly import Inventor models, you'd have to export/import with a neutral format like .step)

Rendering a small assembly takes a while as it goes past through lot of iterations, is there a quicker way to apply rendering ? I have to render 8 models. There is an option in rendering saying until satisfaction..what does that mean I mean who sets satisfaction level ?
Yes, rendering will take a while depending on how fast your system is. Inventor uses the CPU for rendering, so the more cores your processor has, the faster it will go.
The render option "until satisfactory" means it will keep rendering until you are satisfied with the quality and pause it to save the image.
A possibly (slightly) faster way to render would be by using the realistic view/raytrace option instead of going into Studio.

It's how i made the preview image i showed in my earlier post with the tank.
Visual style needs to be set to realistic for Raytrace to work, i also turn on all shadows and set it to perspective.
I chose "the alps" for this, but if you're working with a background image you'll have to play around with the lights in order to match your image.
Depending on which quality setting you choose (low, draft or high) it will take more time to render as well.
The more complex your model, the longer it will take.
Hope this is helpful information for you.
