My first attempt at a tunnel portal

[MXD]

This is all made of styrene with a coat of sculptamold over it. Both the portal and interior wall were done the same way.

Tutorial pleez?

Looks nice. Good job.

Looks very nice. A little too shiny on the rocks but a coat of dullcote will solve that problem.

Thanks guys. I snapped that pic when it was still wet. It actually looks dull now that its dry. I made some more progress so I'll snap a few more pics and get them up with a brief tutorial. I have both inner walls done, the roadbed done and the rock wall between the roadbeds done. I basically cut the shapes out of extruded foam then covered them in sculptamold and textured them.

Here are a couple of more pics. I lightened the color a bit because when I put the top on it looks too black. This is where the two tracks will exit the mountain and come together before entering a small yard.

Looks like a nice blasted bore tunnel. I would be tempted to add some color to the mortar lines on the portal though.

I guess its a good sign that I thought of that already. At least I know my hunches fall in line with the advise of those more experienced. Here is a shot after I added some black to it. Its shiny because its still wet. I will probably need to add another spray.

Very good - I think you're on the right track. Next, try a very thin wash of alcohol with a few drops of india ink added. Paint it on the top if the portal and just let it run down. It will give a nice, weathered appearance to the whole portal.
