It's pretty straightforward, Bobvan.

First, load up your model with the ACSEL shaders you want to transfer, then start up Reality and go to the Materials Tab, select all the materials you want to save the shader from, then click SHADER OPERATIONS to the lower right, and save to a folder of your choice. Save your scene if needed, then load your new model or open the scene containing the model you want to transfer the shaders to.

Once you have loaded the model you want to load the shaders to, select each material you want to load, in the materials tab of Reality,  again click on SHADER OPERATIONS, then choose Load Shaders, select the folder where you saved them (yes, select the FOLDER not files)

and presto! your Shaders are loaded to the new model.

a quick-and-dirty guide to transfering ACSEL Shaders from one model to another

Hope it helps!
