ramRender will load both the previous render and the new render into the Ram Player for easy comparison. ramRender is written in Maxscript and is compatible with Max 2009 upwards.

ramRender is intended as a tool to enable you to compare two version of a rendering. Simply click the ramRender button to activate, and it will then monitor the renderer. When you next hit render, the current image in the Render Frame Window (RFW) will be stored, and then displayed in the Ram Player together with the new rendering. You can then slide the splitter left and right to see the difference between the two renderings.


To access the options panel, hold Shift and click the ramRender button.

‘monitor renderer’ – This indicates that ramRender is monitoring the renderer. Toggle the toolbar button to turn this on or off.

‘remember current render’ – Activate this, and ramRender will remember the image in the RFW and always display this in the left channel of the Ram Player.

‘load image file’ – Click this button to choose an image to load into the left channel of the Ram Player instead of a rendering.

q: what version of 3DsMax does ramRender work with?

a: The earliest version that will work is 3DsMax9, this is because ramRender relies on Maxscript code that was introduced with v9. I have tested it successfully on Max 2009, 2010, and 2011

q: how come there is another ram Player every time I render?

a: Autodesk have not made many controls of the Ram Player available to Maxscript, and this is as much as I could do

q: I would like a feature added or change, is that possible?

a: Yes, if you have some suggestions about how to improve ramRender then I’m all ears. Please comment below

q: What renderers is ramRender compatible with?

a: ramRender is compatible with any renderer that uses the 3DsMax render frame window. This means that it is compatible with VRay, but not the VRay frame buffer. Users of the VRay frame buffer will be able to use the built in VRay Frame buffer History tool that comes with VRay.
